Abstract—The electro-hydraulic systems are commonly used in the motion control applications. This paper represents an implementation of robust control for an electro- hydraulic system of CVT. The robust PI controlled system for speed ratio electro-hydraulic system of CVT is designed for adjusting speed ratio of CVT by using MATLAB environment. The objective of this study was to design the controller of an electro-hydraulic system using the robust PI control system which is to maintain guarantee of the speed ratio electro-hydraulic system performance in spite of model inaccuracies and alteration. The Mathematical modeling of the electro-hydraulic system of CVT is presented in terms of equations. The robustness and tracking ability of the designed controller were demonstrated through simulations. According to the results, the robust PI controlled system for speed ratio electro-hydraulic system of CVT gives the good performance, such as rise time, settling time, overshooting.
