This paper presents the dynamic modeling and simulation of a feedback linearization scheme for high performance induction motor control which decouples the rotor flux and the rotor speed (torque) control loop. In this scheme the controller takes rotor flux from the feedback path and uses it for the cancellation of nonlinearity present in the rotor flux and the rotor speed control signal. As direct...
This paper presents a feedback linearization control scheme with sliding mode controller (SMC) for enhancing performance of the induction motor drive. The feedback decoupling controller is designed in a stationary (α-β) reference frame with rotor flux and stator current components as state variables. Since the induction motor drive system is sensitive to parameter variation and load disturbances,...
Based on mathematical analysis, the dynamic mathematical model of asynchronous motor with iron loss and the model without iron loss are deduced. Using the basic modules and S-function of MATLAB/SIMULINK, the simulation models of three phase asynchronous motor with iron loss and without iron loss are built. Compare the two models with the results of simulations, and give the influence on stator current,...
A phase-difference angle (PDA) controlled pulse width-modulated (PWM) inverter instead of phase voltage modulation and/or frequency changing is proposed to control the speed, and position of a two-phase induction motor. Several characteristics of a two-phase induction motor driven by the PDA inverter are studied to verify the improvement of the motor performances. Also, speed, and position tracking...
