Optimization of automatic controller design coefficients

Classical tuning methods of PID controller, such as the Ziegler-Nichols and Cohen-Coon tuning formulae are able to tune the mentioned controller easily, when they use for controlling the linear system. But, empirical studies have found that these conventional tuning methods result in an unsatisfacto...
