This paper presents a methodology to implement PID (Proportional, Integral, Derivative) controllers in FPGAs (Field-Programmable Gate Arrays) using fixed-point numerical representation. The Matlab/Simulink environment is used for modeling, simulation and evaluation the performance provided by different fixed-point representations using a given control(More)
This paper shows a PID (Proportional, Integral, Derivative) controller, implemented in a reconfigurable hardware, to control the gain of a CMOS image sensor. The main functions of the proposed system are: image acquisition, histogram building, histogram analysis, and PID gain control based on the histogram analysis. The system has several functional modules(More)
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(More)
