Abstract :
A vector-controlled induction motor position servomotor drive where fuzzy control is used to achieve robustness against parameter variation and load torque disturbance effects is described. Both coarse and fine control with the help of lookup rule tables are used to improve transient response and system settling time. The performance characteristics are compared with those of proportional-integral control. Simulation results clearly indicate the superiority of fuzzy control with a larger numer of rules. The fuzzy controller was implemented with a 16 b microcontroller and tested in a laboratory on a 3 hp insulated-gate bipolar transistor (IGBT) inverter induction motor drive system. The test results verify the simulated performance
