摘　　要：针对一类受控对象相对阶可确定的非线性系统,基于系统的预期动力学方程参数,构造出了一种基于相对阶的状态反馈补偿控制器.该控制器可以实现类似自抗扰控制的扩张状态观测,但参数整定比典型的自抗扰控制器大为简化.仿真实验表明:该控制器具有很好的鲁棒性能,其动态性能和抗干扰性能均优于传统的几类常用控制器.Aiming at the nonlinear systems with determinable relative degree,a state feedback compensation controller based on the parameters of the system anticipative dynamics equation was designed.The controller can achieve the extended state observation of active disturbance rejection control（ADRC）,but the parameters tuning is more simplified compared with the classical ADRC.Simulation results show that the controller has good robustness,and its dynamic performance and anti-interference performance is superior to the traditional controllers.
