Switching time estimation and active mode recognition using a data projection method
International Journal of Applied Mathematics and Computer Science, 2016 This paper proposes a data projection method (DPM) to detect a mode switching and recognize the current mode in a switching system. The main feature of this method is that the precise knowledge of the system model, i.e., the parameter values, is not ...
