Abstract :
A vector control system for a slip-frequency controlled induction motor is introduced. The system has a simple structure, fair performance, and convenient operation. It is realized by two single-chip microprocessors and fed from a sinusoidal PWM-GTR inverter. The whole system is combined from two subsystems, both 8031 single-chip microprocessors. The communication between them is coordinated by the full-duplex serial port within the chip in an ask-and-answer communication manner. The adopted error-correcting means has improved the operational reliability of the system. Experimental results on a 3 kW induction motor are given.<>
