Double volume control tank level neurons based on Kingview
Abstract:This paper designs a single neural element self adaptive PID control system of liquid lever of water tanks based on KINGVIEW，VB and MATLAB for the purpose of engineering using. First, this paper elaborates not only the characteristics of this method, but also the control rules. Single neural element self adaptive PID controller is designed with MATLAB for the liquid level model and the simulation is achieved. By combining Matlab and VB, single neuron PID controller ActiveX control is developed and embedded into application program of KINGVIEW, then accessing ActiveX through script. The system uses KINGVIEW to monitor the control process to develop configuration interface, to define variables and devices, and also to achieve dynamic picture connecting. The system uses MATLAB to calculate the control quantity by editing single neural element self adaptive PID control algorithm as a background dominating controller. Then the control quantity is passed to KINGVIEW to control electric valve. The results indicate that the liquid level control requirements are realized and the technical indexes can meet the standard.
