Novel Based Hybrid Fmin-Ga, Based Pid And Fractional Order Internal Model Controller For Compressed Air Pressure Process

The Compressed Air Pressure Process (CAPP) is very important process in an industrial environment. Because the compressed air is used in many applications such as pneumatic based actuation like pneumatics valves, pneumatic based tools etc. In this process the minute linkages, is very difficult to arrest and also nonlinear behavior of conversion elements such as pressure (3 to 15) psi to current (4 to 20)mA (P/I) as well as current (4 to 20)mA to voltage (0–5) v (I/V) converters are making the process highly nonlinear. The nonlinear process to be controlled to maintain the process variable at a particular prescribed value, to design a good and effective controller, best model is needed. In this research work optimized integer and non-integer models are obtained and based on the models the PID controller with optimized controller parameters are selected based on the model using optimization techniques such as Fmin-GA and also the Internal Model controllers (IMC) are designed, the Investigations are done by comparing the dynamic behaviors.
