  • Design of the mechatronic components using dynamic emulation of mechanical loads
    Rodič, Miran ; Jezernik, Karel ; Trlep, Mladen
    An approach to the dynamic emulation of mechanical loads is presented and analysed. It can be used for the testing of variable speed and torque drives, where both, linear and non-linear dynamics, can ... be applied. The experimental system consists of the drive under test (drive machine), which is mechanicallyconnected to the active loading system (load machine). The emulation procedure is performed by the closed-loop calculation of the torque,applied by the load machine, in such a manner that the input/output behavior of the experimental system resembles the one of the drive under test propelling the actual load. A feedback compensation scheme is used, where the input is obtained from the torque observer. The output (model speed) is calculated from the numerical model of the emulated load. The method is simpleand requires no torque measurement equipment. Also the influence of the nonlinear dynamics of the experimental system is presented. The applied load machine (BLDC motor) is assumed to be torque-controlled with high precision. An induction motor is used as a drive machine. Algorithms are developed with the use of Matlab/Simulink and experiments are executed with the use of the dSPACE system.
