Design of a Tuned PID Controller for a Hydraulic System

In the matter of fact this paper aims to design a numerical PID controller for hydraulic system. The estimated model has been used to numerically tune the PID parameter to control the industrial hydraulic system and the step response of the system has been checked. Indeed for a hydraulic system designing an optimal control technique is required. Hydraulic system often uncertain parameters and contain components exhibiting strong friction, saturation, variable inertia mechanical loads, etc. Actually the characteristics of these non-linear components some time cannot known exactly as structure or parameters. So that, tuning of the traditional PID controller parameters to control this system for the required performance faces struggles and drawbacks. In congestion to that, in this paper design PID controller that has the capability to solve the control problem of highly uncertain systems like the hydraulic system.
