“…Several control techniques using conventional controllers have been reported for the control of SEDM [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. The learning ability, self-adapting capability, super fast computing features of artificial intelligence (AI) technology has brought a new challenge to electrical engineers who are struggling with complex, fast advancing, and interdisciplinary areas of technology.…”

This research article proposes the speed control of a separately excited DC motor (SEDM) in the constant torque region. The novelty of this article lies in the application of artificial neural network-based model reference controller (MRC) for the speed control of SEDM. This paper also discusses and compares the speed control systems of SEDM using PI-controlled and fuzzy logic-controlled chopper circuit with MRC. The entire system has been modeled using MATLAB 7.0/SIMULINK toolbox. It has been observed that chopper-controlled speed control system could be eliminated by the use of MRC and the performance of the proposed system is comparable with speed control system using chopper circuit.

“…Several control applications have been done utilizing modern control techniques. Some of them utilize variable structure control (VSC) [1,5,7], optimal control [2,4,12,13], optimal PID control [6,9], adaptive control [10,11], etc. The drawback of using the VSC is mainly due to the concern of excessive chattering.…”

This paper proposes a novel integral variable structure control (VSC) system and a preview control system to control the speed of a dc drive and obtain maximum efficiency over the whole control range. The reduced dynamic equation of the dc @DE-DC) drive system is derived based on maximum efficiency. This is done to simplify the complexity of the control system and hence to reduce the execution time of the microprocessor. An integral action is introduced into the VSC to improve the transient response, minimize the steady state tracking error and reduce the rise and settling times of the drive system. An augmented system utilizing a pure integrator (filter) is introduced into the VSC system to mitigate the input chattering problem of the drive system. A preview controller is also synthesized and implemented with the RDE-DC drive system to maximize the efficiency and control the drive speed. This controller utilizes few future values of the desired signal and disturbance signal. The desired signal is the desired drive speed while the load torque is considered as a disturbance signal. The design procedures and comparisons between the different VSC control systems are made. Matlab simulation studies are carried-out to investigate the feasibility, tracking performance and robustness of the control system with changing the speed, torque and parameters of the RDE-DC drive system.
