| Abstract | A method for modeling a Hydraulic Servo System (HSS) for Hydraulic Mini Press Machine is presented. In this paper, the HSS behaviors of a step and sinusoidal inputs are investigated both theoretically and experimentally. First, we develop mathematical models for obtaining the system res ponses. These responses of the servo valve, and open loop HSS are given step and sinusoidal inputs. While, the closed loop system is based on linearized model of feedback regulator of Fuzzy - P I D controller for high - speed control. All models and controller s are simulated using MATLAB and SIMULINK computer program. An experimental set - up is constructed, which consists of microcontroller PIC 18F458 as controller, a servo valve driven HSS, and feedback elements. The result shows that, HSS can provide highe r speed of response with fast motion of the plant and its performance is compared with three alternative high speed nonlinear HSS. We show, that the maximum velocity of step response is 0.125 m/s after simulation and experimentation. It is shown that, prop osed method is superior to existing ones. |
