Swarm Intelligence in the form of Particle Swarm Optimization (PSO) has potential applications in electric drives. The excellent characteristics of PSO may be successfully used to optimize the performance of electric machines and electric drives in many aspects. It is estimated that, electric machines consume more than 50% of the world electric energy generated. Improving efficiency in electric...

Sinusoidal pulse width modulation is a popular modulation for most alternating current induction motor. It only requires fewer calculations and is easy to implement. However, the shortcomings of using it are low DC voltage utilization, and poor inverter transmission capability. In recent years, there is an increasing trend and more research concentration of using space vector pulse width modula...

This research presents two mathematical –based optimal control systems for induction motor drives leading to stator current optimization and energy saving. The first is a classical optimal control system, which uses information on torque of the motor to generate the appropriate voltage amplitude that minimizes the induction motor stator current. The second is a genetic algorithm-based optimal c...

-Among all the speed control techniques for induction motor drives, Direct Torque Control (DTC) method is simple and efficient because DTC is independent of machine rotor parameters and free from d-q transformation. Modern DTC based drives are equipped with estimators, observers, and machine intelligence systems to improve the dynamics and efficiency of the drive. This paper is aimed to focus o...

Induction motors are an important consumer of electricity. Among induction motors, speed-regulated have the greatest energy-saving potential. However, operating in a very wide speed range require completely different approach than on single supply frequency. An example such drives industrial washing machines. The article aimed to present how using field-circuit methods, but above all, analytica...

The induction motor is without doubt the most used electrical motor because of its unique characteristics. Induction motors are the most common motors used in industrial motion control system due to its low-cost, simple and rugged design. Induction motors drives are widely used to control the speed of conveyor systems, blower speeds, pump speeds, machine tool speeds, and other applications that...
