Electrodynamic Simulation of Inertia Load

Dynamic response in most electromechanical motion control systems is dominated by the rate terms. The need to simulate load often arises in testing such systems or algorithms. This report addresses the issue of stability in dynamic inertia load simulation using coupled machines. A criterion limiting the simulated inertia is derived. No suitable scheme has however been identified to avoid violation of this stability criterion in trying to simulate arbitrarily large inertia load apart from recourse to DSP.
