| Abstract: | Controlled Dynamic System exists in optimal control and other fields. There are expansive errors in the calculation of many useful algorithms including HPD, which can make the result distort. So QR-HPD is designed to solve this kind of system effectively. Both theory and example have proved the availability and high precision of QR-HPD. |
