The Design of Position control system based on DSPIC Digital Processor

Abstract

The development of the electronic technology and the large scale integrated circuit technology is developing rapidly, which makes the computer chip technology get the rapid development.. DsPIC digital signal processor is a combines the 16 bit MCU control characteristics and digital signal processor (DSP) high speed operational advantages of a new type of chip, conforms to the continuous upgrading and high speed, generalization, specialization and improve price and analog digital mixed integrated development direction. This design is the dsPIC digital signal processor as the main control chip applied to bag making machine control system to, is of high performance and low cost of bag making machine control system research of a new attempt.

The design selected dsPIC33EP256MU806 main control chip and build the peripheral hardware circuit, using MPLAB ide development environment to achieve the code written and designed meet the requirements and technical development of position control system.

In the position control system, the key is the design of servo driver circuit based on DsPIC DSP.
