The major objective of this paper is to analyze the imaging performance of the confocal microscopes with varying opto-mechanical conditions. In this paper, the working principles of the one- and two-dimensional scanning mechanisms in the microscopic systems are first reviewed and verified by opto-mechanical simulations. Then, for the imaging performance, the tolerance to the fabrication and assembly of the optical components in conventional confocal microscopes is also investigated by simulations. The simulation results indicate the importance of eliminating the effects of stray light in the microscopic systems.Item Mathematica 程式設計入門(高立, 2003-03-20) 屠名正Item 應用有限元素法於7075鋁合金銲接殘留應力及角變形之數值模擬分析(高雄市 ： 中華民國銲接協會, 2007-09-01) 鄭慶民; 屠名正; 鄭欽源; 范功達Item 以田口法搭配有限元分析之撓性鉸鍊研究之(2008-06-28) 屠名正; 李長憲Item 超精密定位平台撓性結構之研究(2008-11-21) 屠名正; 范功達Item 不銹鋼薄板應用脈衝式雷射銲接之數值分析(高雄市 ： 中華民國銲接協會, 2008-09-01) 屠名正; 鄭慶民; 謝欣涵Item 單一壓電塊實現旋轉定位平台之研究(2009-11-20) 屠名正; 邱弘興; 蔡維倫; 范功達Item 一種懸空結構的製造方法(2009-06-21) 楊啟榮; 林明憲; 李明承一種懸空結構的製造方法,包含下列步驟:(1)提供一矽基板;(2)定義一圖形於該矽基板上,該圖形則具有一保留區與一蝕刻區;(3)以電化學蝕刻,是對該矽基板通以一電場並輔以一蝕刻液進行蝕刻,其中對該電場施以一第一電流密度,將該蝕刻區下方的矽基板去除,致使該保留區下方即形成一預備懸空結構,則該預備懸空結構具有一底部與該矽基板連接;以及(4)改變該電場的電流密度至一高於該第一電流密度的第二電流密度,藉以去除該底部,而使該預備懸空結構懸空於該矽基板上而成為一懸空結構。Item Internal Model Control of Lightly Damped Systems Subject to Periodic Exogenous Signals(Institute of Electrical and Electronics Engineers (IEEE), 2010-05-01) Lu, Yu-ShengThis paper presents an internal model control (IMC) design for lightly-damped systems subject to periodic exogenous signals. For such systems, the conventional design of the so-called IMC filter in the IMC structure can result in oscillatory behavior even when the closed-loop transfer function is designed to be well damped. To circumvent this problem, several band-pass filters are incorporated into the IMC filter based on knowledge of the frequencies of the plant's resonance modes and exogenous signals. The track-following system of an optical disk drive is employed to illustrate the design of the proposed IMC filter. Experimental results confirm the effectiveness of the proposed design.Item Sliding-Mode Disturbance Observer With Switching-Gain Adaptation and Its Application to Optical Disk Drives(Institute of Electrical and Electronics Engineers (IEEE), 2009-09-01) Lu, Yu-ShengThis paper deals with the design of a sliding-mode disturbance observer (SDOB) with switching-gain adaptation for a class of nonlinear systems subject to exogenous signals. The proposed SDOB, referred to as IMP-SDOB, is based on the internal-model principle and thus achieves robust asymptotic disturbance estimation, whereas the conventional SDOB leads to nonzero estimation error to a time-varying disturbance. Moreover, while the conventional SDOB needs a switching gain greater than the magnitude of an unknown disturbance, the proposed IMP-SDOB design releases this constraint and requires only a small switching gain as compared with a conventional design, further alleviating the chattering problem. The stability of the combined controller-observer system is derived on the basis of a Lyapunov analysis. Moreover, in contrast with the previous switching-gain adaptation law that inevitably yields a nondecreasing switching gain and asymptotic convergence of the switching function, a novel adaptation law is proposed to reduce the switching gain whenever appropriate and to guarantee finite-time convergence of the switching function. The effectiveness of the proposed scheme is demonstrated through experimental studies on the track-following system of an optical disk drive suffering from significant disk runout.Item 具有抗反射表面的太陽能電池及其製造方法(2008-01-01) 楊啟榮; 李幸憲; 黃茂榕Item Sliding-mode repetitive learning control with integral sliding-mode perturbation compensation(Instrumentation Systems and Automation Society, 2009-04-01) Lu, Yu-Sheng; Wang, Xuan-WenThis paper proposes a sliding-mode repetitive learning control (SMRLC) scheme with an integral sliding-mode perturbation observer (ISMPO) for repetitive tracking control tasks. The three control strategies which are synthesized to yield excellent tracking performance are: (1) the pole-placement feedback control to specify the desired error dynamics; (2) ISMPO-based feedback compensation as the robust part; and (3) a feedforward learning component that refines the control to improve system performance through repetitive trials. The ISMPO-based feedback compensation ensures that there is only small tracking error during initial learning trials and enhances system insensitivity to exceptional and aperiodic disturbances. The feedforward learning compensation is updated according to a certain switching signal that is equivalent to the compensation error of the feedforward control, yielding fast convergence of the learning process from trial to trial. Experimental results demonstrate the feasibility of the proposed scheme.Item 一種模組化壓床設備(2010-10-01) 楊啟榮; 范志文; 黃孟書; 吳俊緯一種運用於微機電作業的模組化壓床設備，包含：一加工模組，具有一容置體、一加工基座與，一受壓連動裝置，其中該容置體更具有一通氣孔，透過該通氣孔將該容置體內之氣體排出，使該容置體內呈真空狀，而該加工基座設置於該容置體內，該受壓連動裝置設置於該容置體內而與該加工基座面對面，且伸出該容置體外；以及一壓床本體，具有一加壓裝置以及一結合部，其中該結合部用以容置該加工模組，該加工模組與該結合部相結合並可分離，該加壓裝置施壓於該受壓連動裝置。Item 一種陽極接合供電方法(2006-01-01) 楊啟榮; 張淑芳; 吳俊緯; 李致輝Item High-Order Variable-Structure Disturbance Estimators with Applications to Harmonic Drive Systems(中國工程師學會, 2009-09-01) Lu, Yu-Sheng; Hwang, Chi-ShengThis paper describes the design of a high-order variable-structure disturbance estimator (VSDE) that provides asymptotic estimation of unknown disturbances described by polynomial functions of time with arbitrary degrees. In comparison with conventional VSDEs, the high-order VSDE requires only a small switching gain for ensuring the existence of a sliding mode, thus alleviating the chattering phenomenon. Moreover, the transfer function of a high-order VSDE from an unknown disturbance to its estimate can have a high relative degree to enable the estimation of time derivatives of an unknown disturbance while providing adequate high-frequency attenuation. Two high-order VSDEs were implemented to simultaneously observe the motor-side and the load-side disturbances in a harmonic drive system. Experimental results show that the compensation offered by the high-order VSDEs effectively deals with the disturbances induced by harmonic drive gearing.
