In this paper, minimal controller synthesis (MCS) algorithm is used in the case of strain measurement for the first time. The MCS control is an adaptive control method and it can be recommended as a robust controller for the servohydraulic materials testing machine. The algorithm coped with various specimens, which have different materials and diameters. The control accuracy is important in materials testing due to the fact that even smaller overshoots or undershoots can cause Undesirable results in cyclic loading. For this reason, the controller parameters needs to adjusted according to the changes in the plant parameters for acceptable plant output responses.
