Abstract

This report presents the work done on designing controllers for tracking performance of XY table ball screw drive system. There are three critical demands in designing controller for machining operation in many manufacturing environment. The components include high tracking accuracy, high tracking precision and robustness. The evolution of machine tools technology through advancement of the machine tools controller causes the persistent demand of better tracking accuracy in industry of machine tool. The objectives of this project are to design PID and cascade P/PI controllers for tracking performance of XY table ball screw drive system and to compare the controllers through simulation and experimental process. The comparison of the results between the simulation using Matlab software and experimental using absolute plant of Googol Tech XY table ball screw drive system shows the success of the designed controllers in terms of the tracking performance. The controllers are designed based on the analysis of gain margin, phase margin, bandwidth, stability and sensitivity. The designed controllers have fulfilled the rule of thumb for the gain margin and phase margin. For gain margin, the rule of thumb is 4-10dB while phase margin is 30-90º. Cascade P/PI controller designed successfully lowering the tracking error of the system compared to PID controller for experimental work. It is recommended to add another method of analysing the designed controller by visualization using image processing which helps to detect the tracking error of the system easily.
