The Gate Automatic Control Based on Multi-input Parameters, Time-independent and Self-adaptive Fuzzy PID

Abstract

The gate control system has some features such as multiple input parameters, nonlinearity, hysteresis, time change etc., therefore it can’t achieve good results by using traditional PID. In consideration of these characteristics, based on self-adaptive fuzzy PID control, we improved it and created a new time-independent, deterministic fuzzy PID. Then by auto-fusion of multiple input parameters, we have established a multi-input parameters fusion, time-independent and self-adaptive fuzzy PID controller and used it to control the reservoir gate and water level automatically under heavy rainfall. Simulations and experiments have shown that this method can offer faster response, smaller overshoot and better static and dynamic performance.
