Description

This work presents a controller designed for a Series Wound DC (SWDC) motor. We have chosen only magnetically linear model of SWDC motor. As might be perceived, controller design of SWDC motor contains two control loops, Inner loop for armature current control and outer-loop for the control of motor speed by way of torque generated by electrical subsystem. The control techniques shall generally involve the use of transfer function and state space models of SWDC electrical and mechanical subsystems. The inner-loop has to be projected such that it is faster than the outer-loop so that the speed controller dynamics are not altered by current controller system. Our goal is to control this speed along with the help of armature current. As far as the controller design is concerned, the inner loop should be designed such that it should be faster than the outer loop so that the speed controller dynamics are not affected by current controller system. The intention of this study is to use disparate controller to control the speed of SWDC motor.
