| Abstract | ||
| This paper presents a multizonal integral proportional (IP) speed controller for a closed loop speed . . controller of a separately excited .dc motor. The motor is fed from a dc power supply and $epic : converter. Tbis converter offers boih step-up and step-down characteristics of the 'motor terminal voltage. Ah@ performance is achieved with a simple contml circuit having only one switch , (MOSFET) for the proposed system. The output voltage and current are smooth and free of ripples. The converter operates in both open and closed loop speed control. A multizonal IP speed controller is used to overcome the possibility of change in the system parameters. The proposed modeling,and simulation of the system are performed using differential equations which describe the systembehaviour ih the different operating conditions. The rnn up, transient and steady state are presented. Speed control using.multiZona1 IP speed controller is given to satisfy the best required response for the load disturbances. Also, the motor speed can follow the desired reference speed smoothly in the Werent operating zones, The experimental results have ensured the proposed controller robustness, simple, and powerful control application capabilities. The experimental and simulation results of the converter for both open and closed loop speed control system are verified and a good correlation between them was found | ||
