A disturbance utilization control method based on discontinuity information

Abstract

The application discloses a disturbance utilization control method based on interrupted information in the field of automatic control technology, and comprises the following steps: 1) a discrete system model with input channel disturbance interference is established; 2) an augmented system model is established, including an augmented state variable of the augmented system and an augmented system matrix and a control matrix; 3) in view of the possible packet loss in network transmission, a PD packet loss compensation measure is applied to compensate for the lost information; 4) a disturbance observer based on interrupted information is established based on the interrupted information and the information after PD packet loss compensation, and the disturbance existing in the system is effectively estimated; 5) a disturbance utilization strategy is designed to utilize the disturbance and accelerate the tracking of the system output to the expected output; and 6) a Lyapunov stability analysis method is used to propose a condition for guaranteeing the uniform boundedness of the control system, the application can guarantee the anti-interference performance in the case of packet loss, and the disturbance is utilized to improve the tracking speed of the system output to the expected output.
