An active disturbances rejection controller for hysteretic systems
An active disturbances rejection controller (ADRC) is presented for a class of single-input-single-output nonlinear systems with an hysteresis nonlinearity represented by the Preisach model.The designed ADRC controller is composed of the nonlinearity tracking differentiator,the extended state observer and the nonlinearity PID controller.It can estimate disturbances and compensate,according to the information between the input and the output of the controlled object.Thus it automatically realizes the suppression of disturbance.The result of simulation indicates: The ADRC controller with one set of invariable parameters can maintain that nonlinear systems with an hysteresis nonlinearity has ideal tracking effect.
