Statistical Process Control 5 Part 5 ppt

... The second part of the proof - necessity - is much harder to prove. The choice of µ for computations is usually µ = I (3.2 .55 ) Controllability of continuous systems The concept of controllability ... theory of automatic control. Definition of controllability of linear system dx(t) dt = A(t)x(t) + B(t)u(t) (3.2 .56 ) is as follows: A state x(t 0 ) = 0 of the system ( 3.2 .56 ) is control...
