SPEED CONTROL OF DC MOTOR USING FUZZY LOGIC THESIS

A direct current DC motor is supposed to be operated at an accurate and constant speed even if the load on the system is increased or decreased. Simulation results show the effectiveness of the proposed method. For more information, visit the cookies page. Download full text in PDF Download. This makes it a necessity to employ a method to effectively control the speed of a separately excited DC motor.

Many situations demand change in the speed of the DC Motor. Fuzzy Logic Controllers were proposed to achieve the speed control of a DC motor using combined armature voltage and field current by varying the armature voltage in the constant torque region and the field current in the constant power region. It is a robust, easily controllable strategy. We make use of this this strategy to achieve a flexible control of the speed of the Separately Excited DC Motor. Abstract A direct current DC motor is supposed to be operated at an accurate and constant speed even if the load on the system is increased or decreased. Author links open overlay panel A.

The Objective is to understand the Fuzzy Rule base and inference methods and employ them in controlling the speed of the motor. Cookies are used by this site.

Error in speed and the derivative of Error are taken as the inputs to the Fuzzy controller and by selecting suitable membership functions we control the output of the Fuzzy controller which is subtracted from the armature supply and then supplied to the armature. Published by Elsevier Ltd.

In this way the speed of the DC motor is controlled by regulating the armature supply voltage. It is capable of realizing multiple inputs and producing different numerous outputs. Recommended articles Citing articles 0.

A direct current DC motor is supposed to be operated at an accurate and constant speed even if the load on the system is increased or decreased. Many situations demand change in the speed of the DC Motor.

It is a robust, easily controllable strategy. It is very efficient where the precision required is not too high.

Speed Control of Separately Excited DC Motor using Fuzzy Logic Controller – ethesis

We make use of this this strategy to achieve a flexible control of the speed of the Separately Excited DC Motor. The fuzzy logic controllers were designed to be dependent on one another in such a way that the same set of rules were fired at the same time for the two controllers, having the same antecedences but different consequences. The Fuzzy method gives a human like intuition to the control strategy and is self-tolerant to inputs which are no so precise.
