具有网络加塞的离散随机系统最优线性滤波研究

近年来,网络化数据传输广泛应用于控制系统中,控制系统滤波的研究受到了广大学者的关注。数据在网络化传输过程中会出现随机时滞、丢包、衰减、相关噪声等现象,近期还发现存在网络加塞现象,因此,对同时具有这些现象的控制系统进行滤波研究具有现实意义。文章主要研究具有网络加塞和纵向相关噪声的离散随机系统的最优线性滤波。采用状态扩维的方法,在线性无偏最小方差意义下设计最优线性滤波,并仿真例子验证滤波的有效性。

Study on the Development of Water Transport Network for Passengers in the Gulshan-Banani-HatirJheel Lake of the Capital City of Bangladesh

Dhaka, the capital city of Bangladesh is one of the most overpopulated city in the world and traffic jam is the most severe and regular affliction in the daily life. Also, the existing vehicles are not sufficient in compared to the population of the city. People have to spend many hours simply sitting in the traffic jam. This lessens the productivity of people and brings sufferings to them. Gulshan-Banani-HatirJheel area is the busiest regions within the city and face severe traffic jam during working hours. These lakes are totally unused. Therefore, there is a possibility to build a waterways network for passengers transport through these lakes. This will reduce the affliction of people via reducing traffic jam. The proposed transportation networks will also preserve the natural environment of the lakes and bring a source of entertainment in the city life. Many developed cities in the world like London, New York, Paris, Venice, Shanghai etc. already have implemented waterways network inside the city and successfully made the best use of cistern side.
