Torque and speed regulation of induction motors using the passivity theory approach

This paper deals with the passivity-based control of induction motors. This nonlinear control method is considered here mainly from the experimental point of view. Two different configurations have been considered: a current-regulated pulsewidth modulation inverter with hysteresis controllers and a space-vector-modulated voltage-source inverter. Experimental results show that both schemes give precise, fast, and robust torque and speed tracking in the full speed range. The first configuration is more attractive due to its better transient response and reduced complexity
