Research on Trajectory Tracking Control for 3-Axis Servo System Based on Optimal Preview Control Method

This paper researches on trajectory tracking control system theoretically and simulation. It suggests an optimal preview control method to track trajectory in 3-axis servo table system. The objective of this paper is to find a controller that minimizes the power of the controlled output under certain assumptions about the reference signals. In this paper, we study space object trajectory tracking problem for a discrete-time system under the assumption that the finite future values of the reference signal are available at each time instant. We repeat the optimal preview tracking problem for the target signal and pre-viewable in a fixed period of time forward. The paper consists of two parts. In the first part an accurate mathematical model is given, the second part of the paper is the simulation by using MATLAB software.
