Abstract :
In this paper a new method for direct torque control (DTC) based on load angle control is developed. The use of simple equations to obtain the control algorithm makes it easy to understand and implement. Fixed switching frequency and low torque ripple are obtained using space vector modulation. This control strategy overcomes the most important drawbacks of classic DTC. Results show the feasibility of the proposed method, obtaining good speed control bandwidth while overcoming classic DTC drawbacks.
