[理工] [自控]-動態方程式

[hola5566 (hate 119)]

'
x(t) = [0  1]x(t) + [0]u(t)
       [-1 0]       [1]

y(t) = [0  1]x(t)


If u(t)=0  , x(0) = [ 1]   ,  find x(π/2)
                    [-1]


只是想問初值要怎麼代= ="  沒做過這種題目

→ honestonly:取拉式轉換 SX-x(0) = X ,X(s) = (SI-A)^-1 x(0)
→ honestonly:反拉式 可得x(t) 然後帶入t=π/2
推 honestonly:少打一個A  ,SX-x(0)=AX
