An Accuracy Indicator of Control System and its Application in Ball&Plate System
The control algorithm affects the quality of the control system directly, even determines the success or failure of the whole system. When a control system can use a variety of control algorithms, but it is difficult to assess the merits according to precision indicator and time indicator, it needs a new evaluation indicator. This paper puts forward a control accuracy indicator to represent the situation above. It takes the Ball&Plate system as the object, uses classical LQR algorithm and an improved LQR algorithm based on the deviation optimization to realize the positioning control, and repeats several practicality experiments. According to the experimental results, does the comparison and analysis from the perspective of numerous evaluation indicators, the results show that the control accuracy of the improved LQR algorithm is higher than the classical LQR algorithm.
