การแปลงระหว่างฟั งก์ชนั ถ่ายโอนกับตัวแทนปริ ภมู ิสเตต
ในกรณีระบบ SISO ทัว่ ๆ ไป หากมีฟังก์ชนั ถ่ายโอน ดังนี ้
สามารถแปลงฟั งก์ชนั ถ่ายโอนให้ เป็ นระบบตัวแปรสเตตใน รูปแบบบัญญัติ (Canonical form)
1) รูปแบบควบคุมได้ ( Controllability form )
2) รูปแบบสังเกตได้ ( Observability form )
3) รูปแบบทแยง ( Diagonal form )
3) รูปแบบจอร์ แดน ( Jordan form )
