This paper deals with design and implementation of speed controller to control the speed of separately excited DC motor using a class A chopper. The speed of Separately Excited DC motor is controlled to a maximum of its rated speed using chopper as a converter. The speed controller used is Proportional Integral type which reduces steady state error and provides fast control. The parameters of the...
The induction machine is the work horse of the industry. It has rugged construction and is suitable for many high power applications. It has also been a key aspect in revolutionizing the locomotive and the automotive industries. For such automotive applications speed control becomes the driving factor. Hence in this we discuss controlling the speed of 3-phase induction motor using constant volt per...
This paper elucidates Low Cost, High performance Chopper based Four Quadrant close loop control of DC Motor. The drive system realized is applicable to Hybrid Electric Vehicles (HEV's) working in all four quadrants. The drive system has been developed and modeled using Scilab /XCOS. The objective of simulation is to predict the performance of the drive system under realistic operating conditions....
Solar Array Drive Assembly (SADA) requires high precision in positioning of the photovoltaic panels, which can be attained through the use of stepper motors. In this paper, a digital controller for micro-stepping drive of stepper motor using Look up Table(LUT) approach is proposed and is compared to the conventional full-step methodology and the Pulse Width Modulation (PWM) technique used for microstepping...
