Design and analysis of torque control for load drive with dynamic emulation

This paper analyses a torque control structure for load machine used as a dynamometer. Typical area of the use is a mimicking of a mechanical load behaviour in case the mechanical load is not available. Instead of that, the mechanical load is emulated by the load machine with specific torque control. This approach belongs to dynamic emulation of mechanical load methods. Reference torque calculation with particular components for compensation of mechanical dynamics and disturbance torque in the test bench is presented.
