摘要：

With the development of electro-hydraulic servo technology in recent years, precise position control of asymmetric cylinders has become more and more critical. So the mathematical model of symmetric valve-controlled asymmetric cylinder electro-hydraulic system as well as the corresponding position control system is established. In order to solve the time-varying load problem of the system, a controller is designed based on the backstepping control method. Then the Lyapunov function is used to prove the stability of the control system, and a simulation experiment is introduced to check the effects of trajectory tracking with MATLAB. The simulation results show that the designed backstepping controller can achieve precise control of the asymmetric cylinder under the condition of time-varying load.
