Trajectory tracking control of the Lunar Rover

The Lunar Rover trajectory tracking system is a discrete control system under digital situation. Data sampling and information transferring may cause disturbance that could degrade the control performance. This article focus on a real Lunar rover trajectory tracking case, with respect to the sampling interference , transmission delay and energy limitation, a control-sampling co-design approach, which is based on quadric optimal control, is put forward and applied to the real case, in which the overall control quality is optimized. By comparing with the controller get from the classic optimal controller design algorithm, we show the correctness and validity of our method. This article is of valuable reference for controller design and control cycle selecting on lunar rover trajectory tracking.
