Operational Feedback Control of Industrial Process Under Wireless Packet Disordering

The goal of feedback control is to control the operation of the whole industrial process, which is to control the efficiency of industrial manufacture, the consumption of industrial materials and other indexes, which can reflect the operational qualities, by sampling and compensating them and make them steadily operated in estimated range. Traditional operational control method adopts manual setpoints of equipment layer loop. However, this method can't automatically adjust setpoints as industrial process proceeds and will even causes breakdown. This paper proposes an operational feedback control method of industrial process. This paper analyzes the unreliable communication features of wireless network and establishes the model of network communication under packet disordering. Based on this, this paper designs the operational controllers of the system without communication problems and with packet disordering problem. To verify the effectiveness of control method, this paper utilizes flotation industrial process as the background and establishes its mathematical model. Based on that, this paper conducts the simulation experiment using the operational feedback control in both equipment layer and operational layer on MATLAB platform. The final result shows that the designed controller in this paper is effective under the network system with packet disordering.
