RESUMO

This work investigates the operation of three phase induction motors in field weakening and high speed regions. Maximum torque per ampère is imposed by using an indirect vector control strategy. Mathematical models that accounts for magnetic saturation is used for simulations and adjustment of controllers used in control algorithm. The driving structure is characterized by the use of VSI static converter with sinusoidal PWM switching strategy and a vector control technique based on orthogonal components. Investigations resulted in the development of a digital simulation using discrete models that turned out generic and reliable, and an experimental system using a low cost fixed point DSP platform. Simulated and experimental results are included and shown the robustness and efficiency of the proposed control system under different operating conditions.
