| Abstract | A method for modeling a Hydraulic Servo System (HSS) for Hydraulic Mini Press Machine
is presented. In this thesis, the HSS behaviors of a step and sinusoidal inputs are investigated
both theoretically and experimentally. First, we develop mathematical models for obtaining
the system responses. 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 PD controller for high-speed control.
All models and controllers 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 higher 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, proposed method is superior to existing ones. |
