Time-Optimal Velocity Response Control of Induction Motor

On Line Determination of Optimal Hysteresis Band Amplitudes in Direct Torque Control of Induction Motor Drives

In conventional direct torque control (DTC) of induction machines, undesirable flux and torque ripples are produced. These occur since non of the selected inverter's voltage vectors are able to generate the exact voltage required to produce the desired changes in the electromagnetic torque and stator flux linkage in most of the switching instances. In addition, when direct torque control is imp...

Optimal Finite-time Control of Positive Linear Discrete-time Systems

This paper considers solving optimization problem for linear discrete time systems such that closed-loop discrete-time system is positive (i.e., all of its state variables have non-negative values) and also finite-time stable. For this purpose, by considering a quadratic cost function, an optimal controller is designed such that in addition to minimizing the cost function, the positivity proper...

Optimal Sensorless Four Switch Direct Power Control of BLDC Motor

Brushless DC (BLDC) motors are used in a wide range of applications due to their high efficiency and high power density. In this paper, sensorless four-switch direct power control (DPC) method with the sector to sector commutations ripple minimization for BLDC motor control is proposed. The main features of the proposed DPC method are: (1) fast dynamic response (2) easy implementation (3) use o...

Dynamic Performance Improvement of Induction Motor Under Energy Optimal Control

Model Based Control (MBC) is one of the energy optimal controllers used in vector-controlled Induction Motor (IM) to control the excitation of the motor in accordance with the torque and speed. MBC improves the performance of the motor, but it produces ripples in the torque and speed. This paper investigates the opportunity for improving dynamic performance in a three-phase IM operating with MB...
