The mechanical cam is a device capable of transmitting the most varied movement profiles, be it translational or rotational. However, using the mechanical cam, it is possible to transmit only a fixed movement profile, if it is desired to change the movement profile, it is necessary to build a new cam profile. The electronic cam is a servomechanism that appeared in order to solve this obstacle, being used to replace the mechanical cam in some applications. This project presents the simulation of a hydraulically driven electronic cam built in the Laboratory of Automation and Hydraulic and Pneumatic Control Systems from a PID controller (proportional, integral and derivative), a hydraulic proportional valve, a double acting hydraulic actuator, a position sensor and a microcomputer together with a data generation and acquisition device. The operation of the electronic cam, its advantages and its flexibility in relation to the mechanical cam will also be presented, when replacing the movement profiles in a simple way. For this purpose, the electronic cam actuator must accompany the electrical signals generated from different cam movement profiles.
