Mpce Experimental Device Three Level System Modeling And Control Algorithms

The real industrial process conditions does not be had by Reproduce in the laboratory, using a typical experimental device object model is a simulation of the control theory and algorithms into applied technology shortcuts. Level is one of important parameters in industrial processes to multi-function process control device (MPCE) as the experimental platform, flexible configuration of the production process, the implementation of a variety of comprehensive programs, respectively, constitute the primary, secondary and tertiary Level control system. Liquid level control system for the controlled parameter, the system modeling, control algorithm and simulation studies, control the production process for the material balance, maintain production stability, and provide the basis for the operating conditions, to provide for the safe operation of the device Security has practical significance.First, A brief about MPCE-1000 experimental device structure is given, the composition and working principle of three-tier level system based on each level of the relationship between flow and liquid level are illustrated by the level control system,mathematical models were established, through the parameters of the model step response method for identification, using MATLAB software to the established model PID control simulation, the simulation results and the actual curve of the same three level system PID control parameters of the curve results were compared to verify the accuracy of the model; for the existence of liquid level system Time lag causes the controller output and the controlled object output response time of dislocation of the phenomenon exists, the time corresponding to proposed control strategy for dynamic matrix (DM-TCPA), increased levels of control delay system level performance analysis of its closed-loop System stability, the effectiveness of the strategy is shown by simulation results.
