Implementation of Active Vibration Control with Force EstimatorChuang, Chen-Wen 12 September 2002 (has links)
In the control of the vibration structure, active vibration control is an important topic during these years. In this thesis, an active vibration control strategy is proposed to improve the vibration problem in a linear motor positioning system. The main purpose of the present research is to reduce the vibration of the positioning system. A force estimator is applied to suppress extra force produced from a linear motor positioning system. However, uncertain parameters of the system and external disturbance degrade the accuracy of the force estimator. A sliding controller has been designed to enhance the performance of the control system. The performance of the force estimator and the improvement of the control strategy have been discussed thoroughly in this research.
The computer simulation and experiments both show encouraging results of the proposed control strategy. The vibration induced from a linear motor positioning system can be suppressed to the expected amplitude 0.0956 when the linear motor position completed.

Improving the algorithm of the LCD Driver IC inspection equipmentHu, Tsai-Hsien 14 January 2010 (has links)
This thesis would solve the control problem of the contiguous tape which using Reel-to-Reel winder mechanism to load and unload. In the past, some theses solve the speed matching between motors by using specific motor controller or specific mechanism. These designs are too complex and inflexible to suit the variety requirement. In this thesis, I have only used simple vibration mechanism. I hope that the variety requirement could be suited by turning the software. I have compared those results by using different algorithms and different type of sensors. According those results, I wish to find a better control method.
During the experimenting, I found that the discontinuous sensor, like Photo-interrupter can not provide enough information about the vibration mechanism. The controller can not turn the motor speed in a short time. In opposition, when using the continuous sensor, like potentiometer can provide more information including the speed and the location of the vibration mechanism. It even provides the moving direction and acceleration. The controller can tune the motor speed by using typical PID control algorithm. I tuned the P¡BI and D parameter by the method provided by Ziegler & Nichols. When working in the factory, there is no problem!
