Study on Preview Control Theory for Trajectory Tracking Control

Trajectory tracking is popularity in industrial procession, such as machining parts control, high automatic control for a roller of shearer cutting in memory mode, etc. In these cases, trajectory tracked was often artificially pre-determined, and essentially belongs to the fields of predictable control. There are still some shortages in the respect of tracking accuracy and responsiveness among the existing control methods. Therefore, the application of predicted control theory, with the neural network and genetic algorithm identifying the dynamic object model, gives new vigor and vitality to the traditional trajectory tracking.
