本論文主旨有二，一是針對雙可變磁阻馬達的驅動設計出創新且低成本考量下的驅動器，另一個則是以FPGA(XILINX SPARTAN-3 )為控制平台來實現順滑模態控制法則達到最短時間電流追蹤的最佳控制。 經由可變磁阻馬達數學模型之分析與控制理論間之推導，證明本論文所完成的系統整合兼具忍受參數變化能力與抑制外來雜訊干擾能力(順滑模態控制)、以及最短時間(最佳控制)之優越效能。 由於驅動器是在低成本的考量下設計出來的，因此在同時驅動雙馬達的情況下會照成MOS開關共用導致過熱或燒毀的缺陷。 經由技巧性地安排PWM的開關時間，可幫助我們成功地克服驅動器缺陷。
The thesis has two points, one focuses on designing an innovative and low-cost drive for driving double switched reluctance motors (SRM); the other is to use FPGA (XILINX SPARTAN-3) to realize sliding-mode control algorithm which can achieve the minimum-time optimal current control. After reviewing the dynamic model of the four-phase 8/6 poles SRM and deriving control algorithm, proving the system integration that we designed with both the properties of parameter insensitivity and disturbance rejection (sliding-mode control) along with time optimality (Pontryagin's minimum principle). The drive is designed under the consideration of low cost, so it may cause MOS burned-out during driving double SRM. We arrange the on-off timing of PWM skillfully to overcome this drawback.
