INTRODUCTION
Feed back control systems are commonly used in controlling various system parameters like temperatures, speed, level, position etc.
Those control systems normally include set point input actuating signal controlled variable and feed back. In the practical Hydraulic System, it is always observed that the prediction made by using electrical counterparts in mathematics do not hold in practice. Besides due to inherent non liniarities of Hydraulic System, it is also difficult to predict their behavior. Because of this drawback, students get confused and it is having its effect on the thinking process of the students, hence ' EEE' has developed Hydraulic Servo System.
This equipment is able to give the feel and the judgement of actual performance of the system.
It can be possible by varying the values of various parameters and anyone can understand, performance, inter-relationship between parameters.
Initial part of the equipment is the basic servo system. This includes a power-pack, a four way spool valve used as a servo valve, the output cylinder, input and feedback linkages.
A sliding spool type servo-valve supplies fluid to a piston whose motion is feed back through mechanical linkages to actuate the servo-valve and closed the loop.
The translational output is converted into rotational output. The input and output displacements are transferred to recording pens through flexible linkages. A synchronous motor is used to feed paper strip at a constant speed on which input and output curve are obtained simultaneously.
To simulate inertia load on the output side, a load disc is mounted of which weights are clamped and the inertia can be varied.
A damper is attached to the output jack, to study the effect of damping on the output curve.
Damping is varied and its effect on output is observed.
