基于组态王和MATLAB的液位串级控制系统

his paper discusses the method of designing complex control system by blend-programming based on KINGVIEW and MATLAB. The cascade control system for liquid level based on KINGVIEW and MATLAB is achieved. The control object is the two water tanks. KINGVIEW application implements friendly man-machine interface (MMI) and MATLAB application implements cascade algorithm. These two parts connect through DDE protocol. It’s proved that this method is feasible on-line running. Compares the cascade control with single loop PID control on the same object.
