Active Disturbance Rejection Control Tuned by Whale Optimization Algorithm for Electric Loading System

Abstract

The torque load test is one of the key tests in the development of aircraft sidestick. Due to the coupling effect of mechanical structure, the angle produced by aircraft sidestick itself will affected the loaded torque of electric loading system, so that the surplus torque appears. In this paper, a control method is proposed to eliminate the surplus torque of loading device for aircraft sidestick. Active disturbance rejection control (ADRC) uses the extended state observer to collect all the nonlinear uncertainties for compensation. In order to avoid the negative influence of strong coupling of ADRC control parameters, whale optimization algorithm (WOA) is combined to automatically tune the parameters for the state of minimum surplus torque. The simulation results show that compared with PID control, the ADRC tuned by WOA can reduce the influence of sidestick angle disturbance, thus it satisfies the requirement for less surplus torque.
