Power performance of boundary technique on FOSMC based induction motor drives

Abstract

Power analysis of induction motor (IM) consists of active, reactive and apparent power. Those power related to power factor (PF) which indicate the performance of IM. This paper presented the power analysis and power factor of IM using IFOC system (part of vector control). However, IFOC only provides speed regulation but not the robustness under disturbance. In one hand, FOSMC proposed the robustness against disturbance and stability of the systems. In another hand, FOSMC has the disadvantages in chattering phenomenon which increase power consumption. Boundary technique (BT) designed in FOSMC using sat(.) function to reduce the power consumption. As the results, the BT decreases stator current consumption, active, reactive and apparent power. active power has an average decrease of 13.02 percent in the variable of torque load, reactive power has an average decrease of 10.46 percent and apparent power has 12.11 percent. The stator current has an average decrease of 12.53 percent. At no-load conditions, the average decrease in power consumption is 30.05 percent. This value decreases when the torque load increases.
