摘要

Water level system is a classic device for the research of non-linear system control. It is always represented by a First-Order plus Dead Time (FOPDT) model around the equilibrium point. Based on the water level system, different PID strategies (empirical method and Ziegler-Nichols method) are studied for the improvement of control performance. Optimised by gradient descent method, a PID controller based on a radial based function (RBF) neural network is given and applied to an actual A3000 three-tank water level system. From the experiment result, the effectiveness of the proposed method is tested.
