3 Controllability of State Space
A system is completely controllable if there exists an unconstrained control u(t) that can transfer any initial state x(t0) to any other desired location x(t) in a finite time t0tT. nn Controllable nm 제 14강 nn 3 Control Engineering 2009 Subject Name Automotive Automatic Control Month 200X

5 Observability of State Space
A system is completely observable if and only if there exists a finite time T such that the initial state x(0) can be determined from the observation history y(t) given the control u(t). 1n Controllable n1 제 14강 nn 5 Control Engineering 2009 Subject Name Automotive Automatic Control Month 200X
