Abstract (EN): Motion control is a common task in a number of mechatronic design systems. However, it is not always easy for the students to understand the relation between the mathematic models in Matlab (R) and the real system on the desk bench. In industrial control curriculum, the knowledge to find optimal PID parameters that makes the system reaches the setpoint in a short period and become stable with a near zero error, is still difficult to achieve. For this purpose, a hands-on experience is crucial to make the difference. This article presents the development of a servomotor control operated through a manual reference, using an external tuned PID controller. The controller was implemented in LabVIEW, on a windows computer that communicates with the motor driver through a data acquisition board. The setpoint is defined using an angular piezoresistive touch pad sensor (donuts type). By moving the finger across the sensor, the motor copies the movement features, same speed, same starting and end points, thus it can be used in classroom as an experimental setup.
