How can i derive a state space equations from the mathematical model of a 4 phase switched reluctance motor to use for the extended kalman filter ?

I am having problems with deriving the state space equations from the mathematical moedl of the switched reluctance motor so I can work with extended kalman filter to estimate the motor's speed. Can somenone help please it's urgent !

A good place to start with understanding the SRM model is the documentation page of Switched Reluctance Machine (Multi-Phase) and the references therein.
