Due to the inherent disadvantages of DC motors, they gradually have to be replaced by AC motors in industrial applications. However, the mathematical model of induction motors is a highly degree of nonlinear and coupled system. The control of AC motors is considerably more complicated than it DC motors counterpart. Therefor, in this thesis, the analysis of the induction motor drive based on the vector control method, and the design of the current regulators are investigated.
In this thesis the vector control theory is first introduced. The stationary frame current regulator is sensitive to the variation of the load so the synchronous frame current regulator is proposed in this thesis. The hysteresis current regulator which is widely used by the industrial world is also introduced. All the control methods proposed in this thesis are analysis and simulated by SIMULINK soft-ware. As to the hardware implementation, the 80196MC single-chip microcomputer is utilized for implementing the indirect rotor flux-oriented control theory.
