VHDL Realization of Hybrid Control Strategy for a Nonlinear System

The Process Industries are automated to keeping in tune with the changing requirements. It creates the need of a well defined philosophy to cater to the extent of sophistication. The Scheme projects a mechanism to adapt to the evolving scenario and orient a strategy to accomplish the desired objective. A conical tank system is chosen and a methodology designed to eclipse the specified liquid level in it through appropriate hydraulic arrangements. It augurs the need of a well defined control algorithm to charter a corrective action and seeks the role of a state of the art processor to implement the procedure. The self tuning Fuzzy-PI control algorithm is coded using VHDL and is evaluated through Modlsim based simulation to verify its practical viability.
