Design and simulation of a switched-capacitor PID control system using labview simulator

Abstract EN

This paper presents a design and simulation of a switched capacitor PID controller to control the speed of DC motor.

The work is divided into two parts which are hardware design for PID controller and software simulation.

Basic operational amplifier circuit is used for design PID controller circuit.

The PID parameters are calculated and used in LabView program (ver.10) for studying the response of the system.

A crystal Oscillator circuit is used to generate two non-overlapping clocks for switching the MOSFET transistors with high accuracy and stability.

The advantages of Switched Capacitor Circuits are Compatibility with CMOS technology, good voltage linearity and good temperature characteristics.

Simulation results present a good performance for proposed design.
