PMSM Sliding Mode FPGA-Based Controlfor Torque Ripple Reduction

AbstractThis paper presents a torque ripple reduction approach to the direct

torque control of a permanent magnet synchronous motor, using a sliding mode control technique. A distinctive feature of this approach is that, by appropriately parameterizing and implementing the sliding mode controller, the discontinuous nature of the voltage source inverter may be directly incorporated into the design process. The key idea is to incorporate the benefits of the variable structure systems control design and the event-driven sequential control structures in order to raise the system’s performance and control efficiency. A predictive slidingmode controller has been developed, designed as finite-state automata, and implemented using a field-programmable gate array (FPGA). This new FPGA logic regarding torque and speed control has been developed, analyzed, and experimentally verified.

Basic circuit of a voltage source inverter.
