Estimating the term…
The invention concerns a method for adjusting motor parameters in a variable speed drive intended to control an electric induction motor M. The method includes a step for determining differences ΔID and ΔIQ between motor flux current and motor torque current references and measurements, a step for calculating a correction value ΔRR of the rotor resistance and a correction value ΔLR of the rotor inductance from the integral terms of the differences ΔID and ΔIQ, a step for adjusting values of parameters of the motor model based on ΔLR and ΔRR, a step for generating control voltages UD and UQ to be applied to the motor M using said adjusted motor parameter values.
Method for adjusting motor parameters in a variable speed drive intended to control an electric induction motor (M), wherein the method comprises:
Variable speed drive intended to control an electric induction motor (M), equipped with a processing unit (10) including a current regulator block (15) delivering control voltages of the motor (M), wherein the current regulator block (15) comprises:
