Considering that

and solving the equation (1) on derivatives

we get the following system of differential equations:

where

Introducing dimensionless variablesand the dimensionless timeimagine the equations in dimensionless form:

where

- dimensionless transfer function of the nonlinear impedance Converter.

From figure 10, which shows the function H/Wj), we see that it is a piecewise-linear multi function containing Mj+Nj+1 segments with unit slope and Mj+Njsegments with slope-dj. The length of the argument (x, y, or z) of the segments with unit slope equal to 2hjthe length of the argument segments with slope-djequal to 2hj/dj. The coefficient sjspecifies the offset of the function Hj(wj), relative to the origin along passing through the origin of the segment with unit slope is m

This nonlinearity of the transmission characteristics of the first and second voltage converters and Converter current is needed in order to provide conditions for the formation of compound multitracker.

When M1=N1=M2=N2=M3=N3=0 when H1(x)=x, H2(y)=y, H3(z)=z, declared the generator of chaotic oscillations generate chaotic oscillations, corresponding to the equations:

For example, when M=0, N=1, a=1, b=-0.5, A=10, B=9, C=0.3, M1=N1=M2=N2=M3=N3=0, the senior characteristic Lyapunov exponent approximately equal to 0.77 (11)

We now put M1=1, leaving N1=M2=N2=M3=N3=0. The function H1(x) takes the form shown in Fig In this case, the appearance of oscillations in the oscillator will depend on the values of the coefficients of h1and s1specifying the position of the boundary between segments nonlinear function H1(x).

While these boundaries do not intersect with the attractor, fluctuations in the generator will not be different from the case of a linear function H1(x)=x, so as movement along the x coordinate is on the segment of the function H1(x) with unit slope passing through the origin. However, the decrease in h1to 0.4 when the maximum size of the attractor according to the ordinate axis x will exceed the corresponding dimensions of this segment, the phase trajectory will sometimes cross the border between the segments and move on to the segment with slope-d and then to the neighboring segment with unit slope.

When the operating point within the second linear segment with a unit slope fluctuations occur in the generator in accordance with the equations:

because the second linear segment with a unit slope offset from the first axis x on the interval [2h-s]. If we make the change of variables x1=x-2h+s and note thatwe get the system of equations

which is no different from equation (1). Therefore, when the movement on the second segment with a unit slope reproduces the original chaotic attractor, offset from the original on the interval [2h-s] axis X.

When the path again crosses the boundary between segments, the movement will return to the original chaotic attractor, etc. the result is a compound chaotic attractor, uniting two of the same attractor (Fig). Similarly formed integral multitracker with a larger number of Semenov in the composition function H1(x) (Fig).

Similarly, the formation of compound multifraction, consisting of copies of the original attractor, ordered golosa y and z, - for this are the non-linearity of the second non-linear voltage Converter and nonlinear transducer (Fig and pig, respectively).

If both are nonlinear two functions Hj(wj), in the manner described are implemented "two-dimensional" composite multitracker (Fig, 18 and 19).

And finally, when all three functions Hj(wjcontain multiple segments with unit slope, and forms a three-dimensional compound multitracker, an example of which is shown in Fig the description.

The older values of characteristic Lyapunov exponent for different values of the coefficients of equations (3)corresponding to the above situations is equal to:

When M=0, N=1, a=1, b=-0.5, A=10, B=9, C=0.3

in the case of M1=N1=M2=N2=M3=N3=0, the senior characteristic Lyapunov exponent approximately equal to 0.17 (Fig);

in the case of M1=N1=1, M2=N2=M3=N3=0, d1=10, h1≈0.4, s1=0 senior characteristic Lyapunov exponent approximately equal to 0.17 (Fig);

in the case of M2=N2=1, M1=N1=M3=N3=0, d2=10, h2≈5.4, s2≈-2.3 senior characteristic Lyapunov exponent approximately equal to 0.18 (Fig);

in the case of M3=N3=1, M1=N1=M2=N2 =0, d3=10, h3≈2.7, s3≈0.7 senior characteristic Lyapunov exponent approximately equal to 0.18 (Fig);

in the case of M1=N1=M2=N2=M3=N3=1, d1=d2=d3=10, h1≈0.4, h2≈5.4, h3≈2.7, s1=0, s2≈-2.3, s3≈-0.7 senior characteristic Lyapunov exponent is close to 0.18 (Fig).

When these values of the coefficients a, b, a, b, C, M, N, MjNjdjhj, sj, j=1, 2, 3 in the proposed generator are observed chaotic oscillations, characterized by the presence of a compound of strange multitracker consisting of multiple copies of the chaotic attractor is shown in figure 11.

The first and second voltage converters are nonlinear impedance converters, which work as follows (Fig).

The voltage Converter includes a differential voltage amplifier with high gain, with additional current output. The amplifier has a high input impedance at both inputs and low output impedance at the first output. Additional (second) output represents the output of the repeater power supply with you okim output resistance. Its purpose is to generate a current equal to a current flowing through the first low impedance output of the amplifier, so that an alternating current flowing in the first output of the amplifier was equal to the alternating current flowing from the second output of the amplifier (Fig).

Considering the fact that the potential difference between the inputs of the voltage amplifier and the input currents are negligibly small, the voltage drop across the resistor R1 is equal to the voltage drop uCon the capacitor, therefore, the current i1flowing in the resistor is equal to uc/R1, the same current flows in the circuit of the nonlinear resistor RNLthe voltage which depends on the magnitude of the flowing current through it i1and consequently, the voltage across the capacitor uMO(i1)=uMO(uC/R1).

Due to the negligible potential difference between the inputs of the amplifier, the voltage between the first and second outputs of the nonlinear Converter voltage equal to the drop of the voltage nonlinear resistor uMO(uC/R1). Thus the current flowing through the capacitor is equal to the sum of the current i1flowing in the circuit of the resistors R1 and RNLand current iC-i1flowing in the circuit of the first and second outputs of the amplifier. Therefore, through the output of a nonlinear inverter current flows equal to the current flowing through condens the tor (Fig). That is implemented is specified in the formula of the dependence of uMO(uC).

Nonlinear current transducer is a non-linear impedance Converter, which works as follows (Fig). It contains the same amplifier, and a non-linear voltage converters. Since the potential difference between the inputs of the amplifier is negligible, the voltage between the outputs of the nonlinear transducer is equal to the voltage across the inductive element, in addition to equal the voltage on the linear and nonlinear resistors. Through the nonlinear resistor current flow equal to the current in the inductive circuit element. As a result, the nonlinear resistor occurs depending on the magnitude of the current in the inductive element, the voltage drop uFRI(iL), under which the chain linear resistor flows a current iFRI(iL)=uFRI(iL)/R1. At first, low impedance, the output of the amplifier receives the current iL-iFRI(iL), the same current flows from the second amplifier output and the sum current iLflows in the external circuit. That is, the external circuit receives a current flowing in the circuit of line resistor iFRI(iL).

Thus, when connecting inductive element to an external circuit through a non-linear Converter current through the outputs of the inverter current flows FRI(iL), and between them decreases the voltage uL. That is implemented is specified in the formula of the dependence of iFRI(iL).

An example of practical implementation of the selected generator of chaotic oscillations can serve as a scheme with the following parameters.

Let R1=1 kω, C1=0.1 µf, R3=4 kω, R5=500 Ohms, R71=R72=R10=11 kω, I0=333 µa.

Thus, the claimed generator of chaotic oscillations differs from prototype and analogues in which the chaotic signal reconstruction is possible only by changing the parameters of the original chaotic attractor, because it enables you to implement a compound chaotic multifractal received by the amalgamation of the original chaotic attractor with one or more copies thereof, as a result of its restructuring, you can also change the number and mutual arrangement of its constituent components, making the claimed generator has a bigger potential for tuning of the parameters of the generated chaotic signal.
