The problem of controlling the induction motor π-model with magnetic saturation is considered using an adaptive controller with stator current and rotor speed measurement. The new in this paper that in the previous work, only the rotor resistance and load torque can be adapted using the controller but in this work, using artificial intelligent technique, an adaptation of the stator resistance variation...
This paper presents simulation studies on the optimal energy control of an inverter-fed three-phase induction motor (1 hp). An overview of various controllers: loss model controller, search controller and their hybridization are given. Induction motor parameter variations due to temperature rise and core saturation are considered when loss models are derived. Mine hoist drive of a mineral industry...
This paper investigates a new direct torque control (DTC) strategy for induction machine based on particle swarm optimization (PSO). The PSO was used to adjust the parameters (Kp, Ki, Kd) of PID controller. The scheme improves the adjustive capability of PID controller. The new direct torque controlled strategy is considered in detail and it is shown that the use of PSO-PID controller decrease the...
This paper presents the application of PSO for losses and operating cost minimization control in the induction motor drives. In this paper, two strategies for induction motor speed control are proposed. Those two strategies are based on PSO and called maximum efficiency strategy and minimum operating cost strategy. The proposed technique is based on the principle that the flux level in a machine can...
