本論文主要目的在於研製一軟式切換轉換器供電之切換式磁阻馬達驅動系統及從事其速度控制,使其具有高轉換效率及高性能速度控制。為方便從事驅動系統之組立及所擬之研究,首先探究馬達之結構特徵、切換操控原理及電磁轉矩產生特性,並探究了解一些既有用於切換式磁阻馬達硬切式及軟切式轉換器之電路組成、切換控制及特性,以做為研擬所提軟式切換轉換器之依據。接著本論文從事以修正式密勒轉換器供電切換式磁阻馬達驅動系統之組立,並進行其操控性能之量測評估。
軟式切換係降低轉換器切換損失及應力之有效策略,故本論文設計製作了一用於切換式磁阻馬達之零電壓轉移軟式切換轉換器。所提之軟式切換轉換器之主要特色為不需外加電壓及電流感測器,只要在原轉換器電路配接一輔助共振支路,並適當控制主開關之延遲導通及輔助開關之切換信號即可完成軟式切換,而合適之延遲時間可事先估算出。在介紹所提軟式切換轉換器於各工作模式下之操作原理及電路主導方程式後,研擬一設計步驟,以求得輔助共振支路之元件值,及主開關與輔助開關之觸發控制信號。所設計之軟式切換轉換器將以一些模擬及實測結果顯示其性能。最後,本論文將從事所組馬達驅動系統之動態模式估測,以及其量化與模式追蹤速度控制。

The main purpose of this thesis is to develop a soft-switching converter-fed switched reluctance motor (SRM) drive and perform its speed control, such that it can possess higher conversion efficiency and better speed control performance. First, in order to facilitate the establishment of SRM drive and perform the proposed researches, the structural features, the switching operation and the developed torque of a SRM are first studied. Then some of the existing hard-switching converter circuits for powering SRM are surveyed. Accordingly, a modified Miller converter-fed experimental SRM drive is established. And its driving control performance is evaluated by some measured results.
As generally recognized, soft-switching is an effective means to reduce the switching losses of power converters. In this thesis, a zero-voltage-transition (ZVT) soft-switching converter for SRM is developed. It is formed from the traditional modified Miller converter by adding an auxiliary resonant circuit. No extra voltage and/or current sensors are necessary. And the soft-switching of main switches can easily be obtained by applying suitably modified switching control signals for the main and auxiliary switches. Having derived the governing circuit equations in various operation modes, a design procedure is proposed to systematically find the constituted components of the proposed soft-switching converter. The performance of the designed converter is demonstrated by some simulation and experimental results. Through employing the developed converter, the dynamic responses of motor drive remain almost unchanged. As to the quantitative speed control issue, the dynamic model of the established SRM drive is first estimated at nominal case. Then a two-degrees-of-freedom controller (2DOFC) and a linear model following controller (LMFC) are designed and applied to let the controlled SRM drive possess good model following speed control responses.
