In this experiment, a small motor, coupling and shaft assembly is intermittently activated using a signal from function generator which is amplified using a DC motor modelling unit. The function is set to produce a step input by selecting a square wave function at an amplitude of 3 volts and a frequency of 0.5Hz. A signal corresponding to the actual displacement of the motor (θ) is recorded in volts by a digital oscilloscope. This data allows for the comparison between the desired position of the motor as prescribed by the input step function and the experimentally determined position of the motor as recorded by the oscilloscope. The sudden and intermittent jumps in input voltage cause very rapid variations in angular acceleration which causes oscillations in the system. These depend on the natural frequency of the system which in turn increases with higher input gain.
