The invention relates to automatic control systems and can be used in the systems of control objects, the parameters of which are unknown constant or slowly time-varying values. Such systems are, for example, automatic control of aircraft, nuclear reactors, irrigation and drainage structures, turbines, engines, etc. The closest technical solution to the present invention is a self-tuning control system (A.S. USSR №1019400 A, 1983, bull. No. 19), containing a block of job factors, connected in series summation block, the first multiplier, an integrator, a second multiplier, the object of regulation, the outputs of which are connected to corresponding inputs of a unit job of the coefficients, the output of summation block connected to the first and the second input of the first multiplier and the second input of the second multiplier, the output of the first multiplier through an integrator connected to the first input of the second multiplier, the output of which is connected to the input of the object of regulation. The disadvantage of this system is the limited functionality associated with the loss of system functionality when working with non-stationary objects. The invention aims to expand the functionality of the system which we are due to changes in the algorithmic structure of the control. The invention consists in that in the system containing the object control unit job factors, connected in series, the first summation block, the outputs of the control object connected to respective inputs of unit assignments coefficients whose outputs are connected to respective inputs of the first unit summation, the output of the first summation block connected to the corresponding inputs of the first multiplier and the second input of the second multiplier, introduced unit assignments coefficient and the second summation block, and the output of the first multiplier connected to the first input of the second summation block, and a second input connected to the output of unit assignments coefficient, the output of the second summation block connected to the first input the second multiplier, the output of which is connected to the input of the control object. The technical result is to expand the functionality of the system by working with nonlinear, non-stationary objects. The drawing shows a block diagram of the proposed robust nonlinear control systems for non-stationary objects. The system contains a control object 1, block 2 job factors, the first summation block 3, the first multiplier 4, a second summation block 5, block job factor 6, the second multiplier 7, y1,... ,ym- output the coordinates of the control object, U - form scalar control action, satisfying the equation:
where γ1≥0, γ2>0, γ3>0 is constant coefficients; g-m - dimensional numerical vector of coefficients of the block 2 task coefficients selected in accordance with the condition of gallizioli polynomial gTα(λ ), where α (λ ) - the numerator of the transfer function; y-m - dimensional vector of output coordinates of the control object; gTy is a scalar generalized output of the control object. The system operates as follows. The signals from the outputs of the control object 1 goes to corresponding inputs of a block of 2 job factors, which is a block multipliers, in this block is the multiplication of the signal from the 1 output of the object of regulation by a constant factor. The signals from the outputs of the block 2 task coefficients are received at the respective inputs of the first summation block 3, where the fold. The output of the first summation block 3 is supplied to both inputs of the first multiplier 4 and the first input of the second multiplier 7. In the first multiplier 4 is a multiplication of the signal with the output of the first summation block 3 on the same signal. The output signal of the first multiplier 4 is supplied to the first input of the second summation block 5, the and the second input of this block receives the signal from the output of the unit job factor 6, from the output of the second summation block 5, the signal at the second input of the second multiplier 7. In the second multiplier 7 is a multiplication of the signal with the output of the first summation block 3 on the output of the second summation block 5 and thus is formed the signal control. Signal control (robust control law of the form U=(-γ1-γ2(gTy)2gTthe y output of the second multiplier 7 is fed to the input of the control object 1. Thus, the exclusion of the integrator and an introduction to the system control unit summation unit job factor allows you to change the control law that ensures asymptotic stability in a significant simplification of the system.
