Software switch for motion controllers

A software switch is realized to achieve motion control using DC motors. The controller, utilizing an interrupt driven software switch scheme, is capable of implementing several real-time control strategies such as the continuously variable or discrete switching frequency control, continuously variable or discrete pulse-width control and phase control of PWM converters. The control methodology is adaptable to diverse industrial application settings. The switching scheme is implemented using the C++ language environment, on the Industry Standard Architecture (ISA) bus based platform. Implementation in software, provides the capability of executing complex control schemes and supervisory functions which are easy to implement, update and adapt to different applications without much overhead
