Hello everyone,

I want to implement a Kalman filter for a system that implements in PSSE. I need the state space and state transition matrices. Could anyone help me how to find the state transition of the models in PSSE? Thank you so much

to the best of my knowledge, there is no command or routine for that in psse. you can read MODELS.pdf to get the transfer function representation for many (but not all) models and also you can get the corresponding state values if you want, by adding appropriate channels while simulating. from there, you will have to convert it to a state space model using some other software (like MATLAB or python).
