Designand Realization Of Experimentalturntable Servo Control System Based On XMC4500

Servo control is one of the core contents of turntable control. With the developmentof science and technology, the accuracy and reliability of all kinds of servo-relatedcomponents have been improved. The requirements for the accuracy of servo system areincreasing in social production and scientific research. A variety of high-performancedigital controllers are widely applied to the servo control; the realization of manyintelligent control algorithms has become reality. Currently, the computing speed ofdigital controllers becomes faster and faster, the integration level is increasing at thesame time. A huge amount of them have rich peripheral interfaces and are able to beapplied to all types of motors and sensors.Permanent magnet DC torque motor is chosen as the driving element and InfineonXMC4500series chip is chosen as the core. The servo control of position and velocity isachieved. Firstly, this thesis demonstrates the overall design of servo system, includingdrive mode, measuring devices, speed measurement method and system modeling, etc.On the hardware respect, the design of the H-bridge driver circuit, driver protectioncircuit and XMC4500peripheral circuits is finished. On the hardware respect,XMC4500peripheral interfaces are configured to achieve the desired functionality forservo control, such as getting the motor speed and position information. The actualmeasured data verifies the accuracy and effectiveness of the improved M/T methodwhich I have proposed. The Thesis also finishes current loop, speed loop and positionloop parameter and discrete design, so does the realization through software. Finally theiterative learning control method of DC motor has been studied and the effectiveness ofthis method on rejection of moment fluctuation and friction torque is demonstrated withsimulation results.
