Linear Dynamical models of physical systems One of the most used actuators in control systems is a direct current (DC) motor. The general output variable of this actuator can be angular speed or angular displacement motion, but, coupled with wheels or drums and cables, can provide translation motion. This paper proposes a state space model of the DC motor built for constant flux and considering two inputs: supply voltage and resistive torque. The two states of the resulting model are represented by angular speed and step response any of these states can be an output variable for a simulation model. Consequently, the system's model has two inputs and two outputs. For the system's simulation a VI is built where the most important element is a Matlab script which contains the matrices A, B, C, D of the state-space model, the independent variable time and the Matlab simulation function. The motor's parameters are given by digital controls on the panel so that these parameters can be interactively modified. To generate inputs, two case structures are used where the input variables can be set: impulse, step and ramp. Here it is also possible to set the signal amplitude and duration, either by step input or torque N.m. The output signals are live display, either one by one or together, on the WAVEFORM GRAPH.
