无线网络环境下工业过程运行反馈控制方法
Operational Feedback Control of Industrial Processes in a Wireless Network Environment
摘要
Abstract
This paper studies operational control design for a class of industrial processes in which the operational index is transmitted back via wireless networks, whose noise and packet dropout may negatively affect the operational control performance. Firstly, a stochastic process model of operational index is established with the input and output of process control as its input and the operational index as its output. Secondly, a dual-layer model combining process control and set-point feedback control is presented with different sampling rates. Thirdly, a Lyapunov function and a lifting method between multirate systems are adopted to design a process PI controller and a set-point feedback controller to guarantee the stochastic stability of the dual closed-loop control system and that the mean value of steady-state error between the realistic and target operational index is zero. Finally, a simulation experiment on the operational feedback control in an industrial flotation process is conducted to demonstrate the effectiveness of the proposed method.关键词
