lqg_ltr
LQG/LTR (loop transform recovery)設計
呼び出し手順
[kf,kc]=lqg_ltr(sl,mu,ro)
パラメータ
- sl
状態空間表現の線形システム (
syslin
リスト)- mu,ro
``十分に小さく''選択した正の実数
- kf,kc
コントローラおよびオブザーバのカルマンゲイン.
説明
以下のシステムのカルマンゲインを返します:
x = a*x + b*u + l*w1 (sl) y = c*x + mu*I*w2 z = h*x
評価関数:
/+oo | J = E(| [z(t)'*z(t) + ro^2*u(t)'*u(t)]dt) lqg | / 0
lqg/ltr 手法は, 以下のように設定したL,mu,H,ro
に似ています:
J(lqg) = J(freq) ただし,
/+oo * * * J = | tr[S W W S ] + tr[T T]dw freq | /0
そして
S = (I + G*K)^(-1) T = G*K*(I+G*K)^(-1)
