摘要：In Semi-cold regions, the canal water is flow under ice cover and the ice is float on the water. The speed of water level dropping and rising must be controlled strictly to prevent ice break. But in the classic PID control, on the one hand the goal water level is a fixed horizontal line, so the error is large at start and brings large overshot which make ice cover break easily. On the other hand, the control processes and speed can not accurately predict before control which cause the control process as expected. In this paper, a new navigational and guiding canal control algorithm is proposed. In this method, a dynamic navigational goal of water level is set before. Through this controller, the control process will follow the guiding, and the water level change process is controlled well as we expected. The simulations show that the water fluctuation and overshoot are smaller.
