PID Controller Based On The Simulation Human Intelligent Control Algorithm

PID control is more prevalent control technology. However, there are many objects without accurate mathematics model in industrial fields, or the mathematics model is more complex, or with highly nonlinear. Controller with the traditional PID algorithm is highly impossible to get satisfied control effect. Therefore, on the base of the traditional PID, the author affiliates the Human Simulation Intelligent Control theory with the traditional PID control algorithm, which improved the control effect.Human Simulation Intelligent Control can give the corresponding decision-making on the base of identifying all kind of characters of errors. Furthermore, it makes control decision by the way of multi-mode conversion and mode of opened loop combining with closed loop. Depending on agile and artful control mode- identify, decision-making, and do it repeatedly, this control algorithm makes the control quality (celerity, veracity, stability) compatible.The thesis mainly introduced the PID controller based on the Human Simulation Intelligent control algorithm. Firstly, in the Matlab simulation environment, the author analysed and proved the advantage of the Human Simulation Intelligent PID control algorithm over the traditional PID control algorithm. The simulation object is boiler's water-level system. Then through simplifying the Intelligent PID algorithm into a program run in single-chip, the author designed an intelligent PID controller. It has preferable control effects and compatibility, and adapt to standard serial communication protocol. The controller has the figure of simple configuration and cheap.
