Control and Filtering for Discrete Linear Repetitive Processes with H infty and ell 2--ell infty Performance
Repetitive processes are characterized by a series of sweeps, termed passes, through a set of dynamics defined over a finite duration known as the pass length. On each pass an output, termed the pass profile, is produced which acts as a forcing function on, and hence contributes to, the dynamics of the next pass profile. This can lead to oscillations which increase in amplitude in the pass to pass direction and cannot be controlled by standard control laws. Here we give new results on the design of physically based control laws for the sub-class of so-called discrete linear repetitive processes which arise in applications areas such as iterative learning control. The main contribution is to show how control law design can be undertaken within the framework of a general robust filtering problem with guaranteed levels of performance. In particular, we develop algorithms for the design of an H? and dynamic output feedback controller and filter which guarantees that the resulting controlled (filtering error) process, respectively, is stable along the pass and has prescribed disturbance attenuation performance as measured by and – norms

Occurrence and Management of Papaya Diseases after Natural Disaster
為避免蚜蟲傳播木瓜輪點病毒,網室栽培已為台灣最普遍的木瓜栽培模式,台灣因位處颱風帶,颱風來襲期間的強風豪雨,網室次次掀網,均成為木瓜果疫病、木瓜黑腐病、木瓜輪點病、木瓜畸葉嵌紋病、木瓜炭疽病、木瓜蒂腐病等病原入侵的最佳時機。預防勝於治療,為減輕風災及豪雨對網室栽培木瓜帶來嚴重的損失,應選擇避風處、地勢高、土壤通氣性及排水良好地栽植,或設置防風林或防風網,做好排水工程,慎選種植時期,採行倒株栽培,提高植株抗風能力。災後木瓜病害管理需注意園區排水及整畦、田間衛生管理、設施修復、受損植株管理及藥劑防治等工作,以減少果實的損失。
Due to the devastations of papaya ring spot virus , cultivation of papaya in the net house is almost a no choice practice in Taiwan. Taiwan is located typhoon area, and papaya is grown all year round, the net house is easily broken out by typhoon /tropical storms or heavy rains which resulted in the severe occurrence of Phytophthora fruit rot , black rot , ring spot virus , leaf distortion mosaic virus, anthracnose and stem-end rot. In order to reduce the loss from natural disaster, such as typhoon, selection of the planting site to avoid strong wind plus good drainage and soil aeration is very important. If possible, the use of wind-break and enforcement of the net house strength are also very important. In order to reduce the devastating of diseases after typhoons, several practices such drainage, field sanitation, repairing of the net house, and spreading of necessary fungicides are key factors to ensure the production of papaya fruits
