FIELD: physics, computer engineering.
SUBSTANCE: invention relates to engineering cybernetics and can be used in systems for automatic control of a priori undefined nonstationary dynamic objects with periodic action. The result is achieved due to that the system comprises a coefficient setting unit, a first summation unit, a first multiplier, a second summation unit, a delay unit, a third summation unit, a second multiplier and a control object. According to the invention, an amplification unit is excluded and the system further includes an integrator and a third multiplier, wherein outputs of the control object are connected to corresponding inputs of the coefficient setting unit, outputs of which are connected to inputs of the first summation unit, the output of the first summation unit is connected to the first and second inputs of the first multiplier and the second input of the second multiplier, the output of the first multiplier is connected to the first input of the second summation unit and the second input of the third summation unit, the output of the second summation unit is simultaneously connected to the input of the integrator, the second input of the third multiplier and the input of the delay unit, the output of which is connected to the second input of the second summation unit, the output of the integrator is connected to the first input of the third multiplier, the output of which is connected to the first input of the third summation unit, the output of the third summation unit is connected to the first input of the second multiplier, the output of which is connected to the input of the control object.
EFFECT: broader functional capabilities of the system, particularly providing more accurate adjustment of parameters of the controller, which enables to generate a high-quality control signal.
