Digital Signal Processor Based V/f Controlled Induction Motor Drive

Abstract

The TMS320 - based control systems have numerous advantages. The high processing speed of the TMS320 family allows sophisticated control techniques to be used to build a high-precision control system. The experimental results for the V/f control of 3-hp induction motor drives controlled by a digital signal processor micro 2407 TMS320 chip have verified the effectiveness of the proposed scheme. The controller structure design is realized using a dedicated Digital Signal based on voltage/frequency (V/Hz) control scheme Processor, designed specifically for motor that transforms the three phase motor speed into control, the controller structure consists of faster voltage and generating input of sine wave of PWM. Inner sin generation PWM control loops and using these voltage components, the AC induction voltage collection and speed controller loops motor can be handled in the similar way & smooth control is possible.
