Abstract

The invention provides a data-driven anti-interference control structure for controlling uncertain system with unknown gain. The structure is characterized in that the structure comprises an input controller module, an extended state observer module, a filter module, a stacker module, and a control input gain estimation module. According to the structure, an adaptive method is combined with the extended state observer, the design of the data-driven anti-interference control structure for controlling the uncertain system with unknown gain is provided, the structure is quick in response, high inbenefit and high in environmental adaptability, the accurate estimation of a control input gain b0 and effective estimation of unknown uncertainty sigma are realized, and it is ensured that the actual value x of the state parameter of the complex uncertain system converges to an expected value r and the estimated value converges to the actual value x.

Description

technical field [0001] The invention relates to the field of anti-jamming control of uncertain systems, in particular to a data-driven anti-jamming control structure of an uncertain system with unknown control gain. Background technique [0002] PID control is currently the most widely used control method in the field of industrial control, which mainly includes proportional control, integral regulation, and differential regulation. Good stickiness and other advantages. However, the complexity of industrial objects and the ubiquity of internal and external factors such as uncertainty, strong interference, and time-varying properties reduce the accuracy and robustness of PID control, so the application of PID control in complex uncertain nonlinear systems is limited. [0003] Active Disturbance Rejection Control (ADRC) regards the uncertainty generated by the model itself as an internal disturbance, and together with the external disturbance of the nonlinear system as a tota...
