This article is based on the configuration pipeline current capacity and the 2-container water tank fluid position cascade control research.In the commercial run flow control and under the fluid position control background, through the turbine meter, the electric capacity type sensor separately to the pipeline current capacity, the water tank fluid position carries on the examination, take the motorized valve as the implementing agency, matches realizes the current capacity, the fluid position accuracy control by the PID control algorithm.Carries on the simulation simulation using the configuration technology realization to the current capacity examination control system dynamic process, takes the solution control system simulation and the design main simulation software by MATLAB/SIMULINK.
This topic expected achieved the goal is the turbine meter can the ideal examination current capacity size, the electric capacity type sensor be able the rapid response water tank fluid position change, the control algorithm which the motorized valve uses to be able to cause it by fast, the accurate control current capacity, thus achieved the fluid position the overall is stable.This article to its principle, mathematics modelling, the system simulation and the control algorithm will carry on the analysis and the elaboration.
Key words: Current capacity examination, fluid position system, cascade control, SIMULINK, simulation.
