WebApr 7, 2024 · Copy. Cannot compute a stabilizing LQR gain (the Riccati solution S and gain matrix K are infinite). This could be because: * A has unstable modes that are not controllable through B, * Q,R,N values are too large, * [Q N;N' R] is indefinite, * The E matrix in the state equation is singular. WebFrom the help of Matlab I would assume that the output is a minimal realization of a system. To my understanding it means that the output function is observable and controllable. …
