In spite of improvement of AC drive systems, still DC drivers are widely used in industry. One of the problems which might cause unsuccessful attempts for designing a proper controller would be the time-varying nature of parameters and variables which might be changed while working with the motion systems. One of the best suggested solutions to solve this(More)
This paper presents development of a neuro-fuzzy system for performance enhancement of a.c.voltage controller fed induction motor drives. Improvement in motor efficiency and power factor is achieved by suitably adapting the motor flux to optimum point by stator voltage control. The optimum SCR firing angle for each operating point is readily estimated by(More)
