Abstract
A variable-speed induction motor is a nonlinear system, but, for small perturbations about an equilibrium point, it is approximately linear. For the case of “high”-inertia loads a simplified approximate transfer function is proposed that relates speed variations to input-frequency variations. A method of determining the “high” criterion is suggested and computed. Predicted and measured results are compared.Keywords
