Abstract

ADRC technique is the development of nonlinear PID approach. Based on extended state observer, the control effect of nonlinear state error feedback (NLSEF) controller has shown good adaptability to noise and model uncertainty by compensation for them in the control loop. However, there are many effects of nonlinear uncertain factors and outer interference in renewable energy systems connected grid. In this paper, the ADRC is used and a new type nonlinear function is applied in extended state observer and nonlinear state error feedback (NLSEF) controller. Simulation shows that the system is effective with excellent robustness.
