Abstract
A novel predictive VSS switching based current controller for three-phase load driven by power inverter is proposed. Main design specifications are robustness to load electrical parameters, fast dynamic response, reduced switching frequency and simple hardware implementation. To meet previous specifications a switching two types of switching controllers are developed: hysteresis type and predictive type. The voltage source inverter (VSI) is represented as event driven system with 23 modes of operation. The switching among these modes is governed by the supervisory control approach. The regulation with the proposed control law provides good transient response of the brushless BLDC motor control. A new logical FPGA torque and speed controller is developed, analyzed and experimentally verified.
