Design of single channel electro-hydraulic servo system

In this paper an single channel electro-hydraulic servo system is designed to validate compare and explore different control schemes on restraining Additional Torque inherent in force loading system. Also it is discussed how to improve loading performance by improving the electronic circuit. By the feedforward signals of velocity it is expected to expend the bandwidth or even higher and reduce the additional torque. The electronic design theory of loading system was mainly explored and was made experiments on subsystems and the whole system. The PID control technique was used to adjust the parameters.
