Dynamometers are widely used for electric machines and their drive systems assessment, reducing prototyping time for many applications, such as Electric Vehicles machines. Having the same mechanical topology allows changing the control algorithm to significantly improve the overall functionality. Hence, this paper proposes dynamic load emulation by utilizing sliding mode control. The proposed method is characterized by its simplicity, robustness, and low computational effort. A proper sliding manifold is designed in which the sliding manifold contains the desired dynamic. The control signal is derived from that, which consists of two parts; the first part is based on the dynamics of the system, and the second part is a switching function, responsible for the rejection of disturbances. Thus, dynamic load emulation (DLE) can be attained with a fast and precise response to various linear and nonlinear loads based on the mathematical model of the desired load. The desired model of mechanical load provides the speed reference to achieve the desired dynamic by forcing the shaft to rotate at a specific speed. The approach has been validated using a linear and a nonlinear load. The perfect tracking of the reference has shown that emulation still can be carried out despite uncertainty in the model and disturbances
