There have been many studies on the methods used to control DC motors, one of which is proportional-integral-derivative (PID) method. The tuning procedure carried out by trial and error whose results are not necessarily correct, overcome this problem an alternative needed that can achieve a better faster value for process. Our contribution explained conventional PID (Ziegler - Nichols) modifica...

In this paper, Direct Torque Control (DTC) approaches of induction motor (IM) drives has been proposed and it is extensively implemented in industrial variable speed applications. This paper presents a unique direct torque control (DTC) approach for induction motor (IM) drives fed by using a fuzzy logic controller. The intention is to develop a low-ripple high-performance induction motor (IM) d...

DC motor widely used-high precision digital controls. Speed control of dc motor is achieved with smooth starter by using buck converter. Hard switching causes unsatisfactory dynamic behaviour produces abrupt variations in the V & I of the motor overcome by dc-dc buck power converter by PI controller. A separately excited dc motor is used for this simulation. The proposed system with PI control ...

This paper introduces the new ability of Artificial Neural Networks (ANNs) in estimating speed and controlling the separately excited DC motor. The neural control scheme consists of two parts. One is the neural estimator which is used to estimate the motor speed. The other is the neural controller which is used to generate a control signal for a converter. These two neurals are training by Leve...

Renewable energy sources like wind, sun, and hydro are considered as a reliable alternative to the traditional energy sources such as oil, natural gas, or coal. This paper describes modeling and simulations to determine a method for the power performance evaluation of autonomous wind turbine system. A speed control regulator is utilized to control the DC bus voltage. The inverter gate’s signals...

Due to its excellent speed control characteristics, the DC motor has been widely used in industry even though its maintenance costs are higher than the induction motor. As a result, speed control of DC motor has attracted considerable research and several methods have evolved. PID controllers have been widely used for speed control of DC motor. In this paper the using Artificial Bees Colony (AB...
