Based on real-time estimation of noise matrix and grey clustering of statevariable, filter or gain matrix is modulated so as to get an estimation of the state vector.
This article describes a new method of changing the variable of state active RC filter to current-mode filter base on the third-generation current conveyor.

The rotor speed can be tacken as a statevariable of the system by using the Extended Kalman Filter, which based on the vector control of an asynchronous motor.
