Finite State Predictive Torque Control with Switching Table for Induction Motor Drive

In the last ten years, Finite State Predictive Torque Control (FS-PTC) is being studied extensively due to many great features such as simple structure, easy implementation, low torque ripple. However, FS-PTC has two main disadvantages. Firstly, the computational burden is large because it uses all possible vectors within a predictive horizon. Specially, the computational burden rises very fast, if converter has many voltage vectors or predictive horizon is long. Secondly, the choice of weighting factors are difficult. This paper proposes FS-PTC with switching table structure to eliminate the choice of weighting factor and reduce computational burden.
