Kalman Filter as Part of a Relay-Vector System Control of Asynchronous Electric Drive

The algorithm of the discrete extended Kalman filter as part of the relay-vector control system was developed for the purpose of identifying the speed and vector of flux coupling of the rotor an asynchronous machine. The dynamics of the control system with the joint operation of the relay regulators and the digital Kalman filter algorithm built into its structure for real-time identification of the state variables of the asynchronous machine were studied.
