The drive of the manipulator operates as follows. Its input is the impact of αIproviding the required control law of the generalized coordinate q3(see figure 2). At the output of the adder 1 is the error signal ε, which after correction in elements 2 and 3, amplified, is fed to the input of the electric motor 5, causing his shaft into rotational motion direction and speed (acceleration), depending on the magnitude of the incoming signal U and the external torque impact Minon the drive.

where Jsithe moments of inertia of the respective links of the manipulator relative to their longitudinal axes; JNithe moments of inertia of the respective links of the manipulator relative to the transverse axis passing through their centers of mass (i=2, 3), g is the acceleration of free fall.

This equation is based on the Lagrange equations of the second kind.

Taking into account the relations (1)and equations electricand mechanical

As a result, in the process of the considered drive change (though significantly) its dynamic properties. Therefore, to carry out these tasks, it is necessary to form such an adjustment device, which was zastabilizirovalis would be the settings for this drive so that he was described by the differential equation with constant desired parameters.

The second positive input of the adder 13 (from the sensor 15 has a gain of l2l3/iPand his first positive input (unit 12) is the unit gain. The output of generator 12 is equal toand output unit 16 -. The second (from the side of the block 19) and third (from the side of the knob 16, the positive inputs of the adder 18 have a unit gain, and its first positive input (- side sensor 15) - gain.

Thus, at the output of the adder 13, a signal is generated. Functional Converter 24 generates a signal cos q3. The sensor 23 measures acceleration. Therefore, the output of block 19 a signalat the output of the adder 18 is a signaland the output unit 22 is a signal

The sensor 14 measures the speedand functional Converter 25 generates a signal sin q3. Therefore, the output BL is ka 21 a signal . The sensor 26 measures the angle q2functional transducer 28 generates a signal sin(q2+q3). As a result, the output unit 29, a signal is generated.

His second (unit 16) and third (from the sensor 15) positive inputs are respectively a single gain and the gain is equal to. As a result, the output of the adder 41 a signal.

The amplifier 30 has a gain equal to 2. Functional Converter 31 performs as a sin. As a result, the output unit 32, a signal is generated.

Since functional Converter 35 implements the sin function and functional Converter 42 - cos, the output unit 37, a signal is generatedand the output of the adder 33, the first (from the side of the block 32) and the second positive inputs of which are respectively the unit gain and a gain equal to 2, a signal is generated

The sensor 43 measures the angle of rotation q1. Function the national transducer 44 implements a function cosq 1. The sensor 47 measures acceleration. Therefore, the output of block 48, a signal is generated.

Functional Converter 49 implements a function sinq1. The sensor 52 measures acceleration. Therefore, the output unit 53, a signal is generated

Taking into account the above-mentioned gain the respective inputs of the adder 11 outputs its signal

The output unit 3, a signal is generated.

The first positive input of the adder 4 (from unit 3) has a gainthe second positive (from the adder 11) - gain R/(KMKy), and the third positive-side adder 2) - gainwhere JH- the desired value of a given moment of inertia, ensuring considered to drive the required dynamic properties and quality indicators. As a result, the output of the adder 4 is formed the signal

It is easy to show that sincewhen the movement of the actuator accurately corresponds to MPthen, substituting the obtained value U*(3) in equation (2), p is the best equation that has a constant desired parameters. That is, the actuator that controls the coordinate of q3will have constant desired dynamic properties and quality parameters.
