Proportional Integral Derivative (PID) controllers are widely used inmany fields because they are simple and effective. Tuning of the PIDcontroller parameters is not easy and does not give the optimal requiredresponse. especially with non-liner system. In the last two decades manyintelligent optimization techniques were took attention of researchers like:Genetic Algorithm (GA) and Par... https://www.roneverhart.com/Cyspera-Pigment-Corrector-1-75oz-52ml/
