Control system design method
| DWPI Title: Nonlinear control system designing method for e.g. transportation device, involves creating stable control system, and employing resulting control system to control physical apparatus |
| Abstract: A control system design method and concomitant control system comprising representing a physical apparatus to be controlled as a Hamiltonian system, determining elements of the Hamiltonian system representation which are power generators, power dissipators, and power storage devices, analyzing stability and performance of the Hamiltonian system based on the results of the determining step and determining necessary and sufficient conditions for stability of the Hamiltonian system, creating a stable control system based on the results of the analyzing step, and employing the resulting control system to control the physical apparatus. |
| Use: Method for designing a nonlinear control system for a physical apparatus e.g. manufacturing apparatus, electronic apparatus, communications apparatus, transportation apparatus, computer apparatus, computer network, military apparatus, electrical power grid, supervisory control and data acquisition apparatus, pipeline apparatus (all claimed), satellite spacecraft apparatus and distributed/decentralized energy apparatus. |
| Advantage: The resulting control system is employed to control the physical apparatus so as to design the control system in an efficient manner. |
| Novelty: The method involves representing a physical apparatus to be controlled as a Hamiltonian system, where the Hamiltonian system comprises a mass-spring-damper dynamic system. Elements of the Hamiltonian system representation, which is power generators, power dissipators and power storage devices are determined. Stability and performance of the Hamiltonian system are analyzed. Necessary and sufficient conditions are determined for stability of the Hamiltonian system. A stable control system is created. The resulting control system is employed to control the physical apparatus. |
