The idea orients to develop a PI controller for closed loop speed control of chopper fed dc drive. PI controller is one of the most preferred controller for speed control of dc drive, which can be easily understood and implemented in practice. The speed of the chopper fed separately excited dc motor can be regulated from below and upto rated speed by using a chopper as a converter. The signal corresponding to the speed error of the motor and change in speed error are given as inputs to the PI controller. The controller output provides the required gating signal that is used to vary the duty cycle of chopper. The chopper firing circuit receives signal from controller, gives variable voltage to the armature of the motor for achieving desired speed response. Modeling of chopper fed dc motor is done. Two loop control system is designed, one for current and another for speed. The complete model of proposed system is simulated using MATLAB (SIMULINK). Also the performance of the simulated model is investigated by using various controller tuning methods.

Adaptive Pid Control

The paper designs a high power DC motor closed-loop control system, mainly including design of H bridge drive circuit, speed detection circuit and signal conditioning circuit. In order to improve the performance of motor running, one proposes a fuzzy adaptive PID control algorithm. Firstly, one determines the degree of membership of the input values to defined fuzzy sets, then constructs the fuzzy rule table according to experience and experiments, finally, makes defuzzification for every parameter of PID controller, that is, Kp, Ki, Kd. Experiments show that both hardware implementation and software control algorithms are reliable, the running performance of the system is robust before or after adding load.

- Brushless Direct Current (BLDC) motors are highly efficient motors with high reliability and a longer life span. The advent of sensor less technology has improved the performance and reliability of BLDC motor drives. This work is to analyze a drive system for BLDC motor with Four-Switch Three-Phase Inverter (FSTPI). Back Electromotive Force (EMF) Zero Crossing Detection (ZCD) method is used to estimate the rotor position. Speed control of motor is achieved by using Fuzzy Logic Controller (FLC) based closed loop control system. The Simulation was carried out using MATLAB software and motor the performance was analyzed with FLC for motor speed regulation.
