自抗扰控制在电液伺服系统中的应用研究

Application of Anti-disturbance Rejection Controller in the Electro-hydraulic Servo Systems

针对某大功率电液伺服系统存在严重非线性、时变性和强干扰问题,为保证系统的静、动态品质,采用自抗扰控制器(ADRC),使系统具有很强的鲁棒性。仿真表明,所设计的自抗扰控制器能够保证大功率电液伺服系统的静、动态性能。

There have too many nonlinearities, time-variation and strong disturbance in the electro-hydraulic servo systems. In order to solve those problems, ensure the static and dynamic performance, an anti-disturbance-rejection controller was presented, which can ensures robustness. The result of simulation ＂shows the presented anti-disturbance-rejection controller can ensure the static and dynamic performance of electro-hydraulic servo systems.
