Digital Simulation of DC Motor Control System

Simulation methods are widely used in system analysis. An ATLAS digital simulation package is used to model and simulate complete DC motor drive control system. DC motor drive is modeled using transfer functions in Z domain. Controller of the drive is composed of a microprocessor with memory, D/A and A/D converter. Detailed model of a controller and satisfactory approximation of the drive makes possible testing and examining behavior of microprocessor controller. Model implemented in ATLAS enables the determination of optimal hardware and software solution for a desired control algorithm. Described model is extensively used for teaching principles of real time computer control.
