Thasli Thaju, Nasar A

Abstract: For modern Mechatronics system, high accuracy position control is inevitable. Electro hydraulic servo systems are widely used in industrial applications because of its several advantages. Position control of servo system is very important for industrial applications. This paper includes modeling, linearization and position control of Electro hydraulic servo system (EHSS) using conventional PID controller as well as fractional order PID controller which is optimized using PSO algorithm were implemented. MATLAB/SIMULINK platform is used.
