Research on Control Strategy of Electro-hydraulic Servo Actuators Based on Strict Feedback Model
The active suspension might adjust the suspension parameters according to the real-time status of the vehicles,which greatly improved the rescue efficiency of emergency rescue vehicles.Electro-hydraulic servo actuator was the core component of active control of electro-hydraulic servo active suspension system,the control strategy of electro-hydraulic servo actuator was studied.The ac-tive suspension hydraulic servo actuator model was established.Then,based on the model,an adap-tive position tracking control strategy was proposed based on a strict feedback model,and the stability of the proposed strategy in the Lyapunov sense was proved.The simulation and single-cylinder experi-ments show that the position tracking algorithm proposed may effectively improve the position track-ing performance of electro-hydraulic servo actuators compared with the traditional control methods.
