STUDY OF PID CONTROL SYSTEM

Ex No: Date:

AIM:-

To study about PID control system.

DESCRIPTION:-

Any industrial drive undergoes run time variations from a process present valve in various

process parameters like speed, temperature and pressure etc., these variation occur due to different

reason like variation in input, loading patterns etc., routing in degradation of the quality of the final

product for example the variation in temperature in a food processing industry may affect the quality

of food product or variation in speed may affect. The quality of job in a machine CNC. The PID

control system is a technique used to control different types of process employed in an industrial

environment. The industrials process may involve slow changing parameters like temperature.

A proportional integral and inlet temperature control system consists of a set of present run

time parameter. The machine process runs according to the present control valves. When these in a

deviation more than the tolerance limits, one or more of the run time tolerance limit. If the error valve

is beyond tolerance then necessary corrective taken by system.

The corrective action components for the quantum of error and control the operative present

limits. For Example:-

Consider the following is a speed control applications. Let the present speed be 1000 rpm. As the

motor is switched on the motor actuates reaches the speed of when a load is applied to the motor shaft

and amount of decrease in speed is proportional to the applied load.

Thus the reduction in speed is measured by sensor and sent to the control system as an error

signal is the speed. Thus the control sequence repeats whenever a deviation about tolerance limit in the

speed. Two process control application are provided with the system normally they are described as

follows motor speed control an example for that changing parameters lies speed.

RESULT:-

The performance of the PID control system in monitoring and controlling the speed of motor

by the two different modes has been studied.
