This paper proposed the new control method of the sensorless dual parallel Induction motor drive system which can maintained the steady speed under unbalanced load condition. This method uses new modified observer design technique for mono inverter dual drive system of same parameters and ratings connected in parallel. The simulation work has been reported for different step changes in speed for balanced...
This paper, deals with a new input-output sliding mode linearization control for induction motor combined with field oriented control (FOC). To control the speed and rotor flux modulus, we develop two loops. The first one, inner loop, allows to linearize the system by a choose of closed loop poles to achieve a good linearization. The choice of a particular sliding surface permits to create a link...
This Paper presents a Particle Swarm Optimization (PSO) method to determine the optimal proportional-integral (PI) or proportional-integral derivative (PID) controller parameters, for speed control of a Field Oriented Control (FOC) induction motor. The FOC induction motor has been modeled in MATLAB (Simulink) and the PSO algorithm has been programmed and implemented in MATLAB. Comparing with traditional...
Present work shows the merits of space vector modulation direct torque control(SVM-DTC) over the conventional direct torque control(conventional DTC). SVM-DTC technique is helpful in solving the basic issues of torque ripple and variable swithing frequency present in the conventional DTC. In order to get the reference voltage vector which is necessary for the SVM-DTC, this paper describes a method...
The dynamics of the induction motor drive can be made independent of the position as well as speed control by using the field oriented control strategies. There are various techniques available under this category. One of such strategies is Indirect Field-Oriented Control method for the Induction motor drive. The speed control is observed in both, open-loop and closed-loop control applications. The...
The main result presented in this paper is the implementation of optimal control based on quadratic criteria into a low power electric drive with three-phase induction motor. The dSPACE 1104 controller has been used in order to obtain the on-line optimal solution of matrix Riccati differential equation (MRDE). Based on the optimal solution and on corresponding feedback signals, the optimal speed reference...
This paper describes an analysis method for achieving control torque and speed with vector control for induction motors. An indirect field-oriented output feedback motor controller is presented; it is suitable for low-cost applications. A current model control is used to sense back electromotive force (back-EMF) by means of an analog to digital converter (ADC); its simulation and filtering are discussed...
In this paper, we studied the vector control with orientation of rotor-flux by using PI regulators for an induction machine without speed sensor, and with adaptation of the rotor resistance. The rotor speed is estimated by using the model reference adaptive system approach (MRAS). This method consists of using two models. The first one is the reference model and the second is an adjustable one in...
In this paper, we present a Direct Torque and Flux Control (DTFC) scheme of an induction motor operating with a stator resistance PI estimator. The variation of stator resistance due to changes in temperature or frequency degrades the performance of this control strategy, and therefore is a big issue of DTFC. In order to solve this issue, a method of stator resistance estimation using a proportional-...
