This trainer allows the investigation of control system principles by using a servo mechanism comprising a DC motor, a variety of digital controllers. Students are also introduced to the fundamentals of signal processing.

Prior knowledge of very basic electronics is assumed as well as simple mathematics although the use of mathematics is minimized as much as practicable. The curriculum is divided more than 20 assignments ranging from basic control concepts to more advanced methods such as fixed point PID control. Selective use of the available assignments allows the trainer to be used from vocational through to higher technician and  undergraduate courses.
