Preview Predictive Control for a Class of Following Systems
一类跟踪系统的预见预测控制算法的研究

Future information is very important to improve following accuracy in a class of application, such as CNC (computerized numerical control) machining, welding. A novel preview predictive control is proposed, to make the best use of future trajectory information. Meanwhile overcome modeling error and disturbance. Simulation shows the new method can improve system following accuracy distinctly.
