Fixed-Switching Frequency Finite-State Model Predictive Thrust and Primary Flux Linkage Control for LIM

The special design of linear induction machines (LIMs) leads to adverse effects caused by the longitudinal and end effects. These make thrust control LIMs most attractive because its value decreases sharply with speed increase. Thus, finite-state model predictive (FS-MPC) is developed increase performance LIMs. However, variable switching frequency main drawback this control. Consequently, objectives paper are propose FS-MPC a constant frequency, directly speed, overcome problems resulting from Therefore, proposed based on primary flux linkage (TF) concept. In addition, effect considered during modeling method. FS-MPTFC method has been tested under different working cases using MATLAB/Simulink check validity. Parameters 3 kW arc machine have used simulation results.
