Abstract: The paper deals with behavior of Multi Input Multi Output (MIMO) state space models for different types of inputs. To achieve a satisfactory response the study of plant control is necessary. The standard input signals are analyzed by taking a state space industrial D.C servo motor model. The model is built using control and simulation loop present in Lab VIEW software. The responses depend on the values of state-space matrices, magnitude of the gain provided in the feedback mechanism and also on the behavior of the continuous linear systems like Integrator and Derivative functions.
