The application presents a MATLAB Simulink model regarding optimum tuning of an adaptable hydraulic system with secondary control aiming to obtain the optimum in conformity with the adopted criterion. It is known that the perturbations occurring in the system are relevant. Therefore, from the possible solutions giving responses of the system according to the input signals (ensuring the imposed performances), the solution conducting to the best behaviour must be chosen. To this end, a series of parameters of the simulation scheme will be modified, according to the theoretical requirements of tuning an adaptable system.
