hello!!!

When the Lombergo observer is used, the Angle estimated by the observer differs from the real Angle by 180 ° sometimes,In this case,The closed loop will fail.I modeled and simulated the algorithm with simulink,It still happens.I think the algorithm has two stable points of 0° and 180°,but how to identify and use them,I hope to get your help,Thank you very much!!!
