Model and Control of Differential Electronical Cam

Jan Adamčík, Martin Tukač, Jan Pelikán, Zbyněk Šika, Michael Valášek


The paper deals with the model and control of the differential electronical cam. The dynamic properties including the flexibilities of important bodies have been modeled. The system is controlled by two electrical motors, one of them is controlled standardly in order to satisfy its constant angular velocity.
The total output motion is composed from the motion realised usin´g the cam profile and the accurate motion controled by the second motor. The synthesis of control law for this second motor is the second main topic of the paper. The influence of flexibilities and the applied sensors are also discused.
