Design of auto disturbance rejection controller based on field-bus

Combining field-bus technology and auto disturbance rejection control algorithm, a new kind of controller is designed. The Rs-485 and CAN bus communication circuit, analog input and output circuit are constructed by using C8051f060 single-chip, where controller software are developed by C51. The experiment results show that the tracking performance is excellent with small overshoot. Meanwhile, it has the merits such as strong anti-interference ability, wide application scope, convenient use, with high promotion and application value.
