This paper introduces an alignment method using machine vision feedback control method. A panel is placed on a XXY table and its posture is inspected by image sensors with a frame grabber. The alignment of the panel is corrected by adjusting its positions until the amount of misalignment converges into a small tolerance error. Two-phase control process is also derived with this image acquisition design. Applying this proposed control method, long distance moving requirement and better alignment precision performance request can be also guaranteed. Experimental results are shown to demonstrate the feasibility of this alignment control system.

Feedback Control Method

In this study, a new controller to prevent the yaw instability and rollover of a three-wheeled vehicle has been proposed. This controller offers the most obvious opportunity for affecting the vehicle's lateral dynamics performance on the full range of nonlinearities during various operating boundaries. The active combined controller has been designed based on sliding mode control method using an active roll system and an active braking system to dominate the uncertainties of the nonlinear dynamic model. Firstly, to avoid rollover of the three-wheeled vehicle, the roll angle was considered as the control objective, and the anti-roll bar was employed as an actuator to produce the roll moment. Secondly, to increase the maneuverability and lateral dynamics enhancement, an active braking system was designed. In the control system, the yaw rate and the lateral velocity were regarded as the control variables to track their references. Moreover, to verify the performance of the mentioned combined controller, another control system has been designed using the linearization feedback control method. Then, computer simulation has been carried out with a 12 degrees of freedom dynamic model of the three-wheeled vehicle called the delta. Furthermore, a nonlinear tire model has been utilized to compute the longitudinal and the lateral forces. Next, the comparative simulation results confirmed the effectiveness of the robust control system to raise the vehicle's maneuverability and its rollover stability in comparison with the linearization feedback control method, especially when the three-wheeled vehicle is subjected to critical conditions.

Training Control

At present, basketball training needs more scientific training methods and techniques. In order to obtain these training methods, it needs to acquisition training information in the process of basketball training. Therefore, in view of basketball training to establish information control system, research on basketball players training characteristics and the law of motion in the process of basketball training, using control theory method to carry out information processing and analysis, and then the use of scoring methods carry out the authority score evaluation on basketball trainings influencing factors, according to the weight values, these are obtained on the basis of the score, then to carry out add sum, finally to obtain the evaluation scores of basketball training information control system. And then according to the weight value, to undertake an analysis of the basketball training control process, the basketball training information control method is put forward. The analysis results show that information control system is mainly manifested in the basketball training information collection and transmission, training scheme decision of coaches decision system as well as the feedback of decision information, which will complete the whole system construction of basketball training information control.
