Dynamic Matrix Control for ACU Position Loop
For a closed-loop control problem of position loop in servo system with an integral process in TT&C (Telemetry, Track and Command) ground station, this paper studies the optimal control strategy, which combines the improved dynamic matrix control (DMC) algorithm with feed-forward compensation.The predictive truncation error of the above system can be avoided by modifying the shift matrix of original DMC;the lag of system response can be effectively overcome via adding feed-forward compensation.The validity of the algorithm is verified by a simulation example, which shows that the set point and the target curve can be well tracked using this control strategy and the strategy can be applied to the position loop control of antenna control unit (ACU) in servo system.
