Cho phương trình sai phân: y(k) = -2y(k-1) +0.5(k-2) -0.2y(k-3) +0.5u(k) -0.4u(k-1) +0.1lu(k-2) Hệ phương trình trạng thái là: trang 66 ĐKS

\(y\left. k \right.=\left[ -1.4 0.35 0.1 \right]\left[ {x}_{1}(k){x}_{2}(k){x}_{3}(k) \right]+0.5u(k)\)

\(y\left. k \right.=\left[ -1.4 -0.35 -0.1 \right]\left[ {x}_{1}(k){x}_{2}(k){x}_{3}(k) \right]+0.5u(k)\)

\(y\left. k \right.=\left[ -1.4 0.35 0.1 \right]\left[ {x}_{1}(k){x}_{2}(k){x}_{3}(k) \right]-0.5u(k)\)

\(y\left. k \right.=\left[ -1.4 -0.35 -0.1 \right]\left[ {x}_{1}(k){x}_{2}(k){x}_{3}(k) \right]+0.5u(k)\)
