In order to provide insights into common video system design problems, several issues for real-time video coding have been addressed in this dissertation, which are video coding computational complexity reduction, rate control, error control and error resilience 本文主要從實時視頻應用角度,對混合mc-dpcmdct視頻編碼中的處理復雜度、碼率控制和差錯控制這三方面問題展開了深入的研究。
The influence of actuators on the dynamic performance of aeroengine control systems, and the intermediate state control systems design problem for certain model of aeroengine based on multivariable h, controller design theory was investigated 摘要為探討執(zhí)行機構對航空發(fā)動機控制系統(tǒng)設計的影響,采用多變量h(下標)控制器設計方法進行了某型航空發(fā)動機中間狀態(tài)控制系統(tǒng)的設計,利用數(shù)字仿真平臺進行了有無執(zhí)行機構時控制系統(tǒng)的對比仿真。
Secondly, the non-linear model of ship motion was studied . the non-linear term and the term related to pitching velocity are referred to disturbance of the system to get state feedback designed mathematic model of the rudder / fin joint control system . the non-linear rudder / fin joint control system-designing problem was transformed into disturbance attenuation linear system designing problem, which uses quadratic performance as object function 為了得到船舶舵鰭聯(lián)合控制系統(tǒng)的狀態(tài)反饋h~設計的數(shù)學模型,把非線性項及與橫蕩速度相關的項也看作是對系統(tǒng)的擾動,把非線性船舶舵鰭聯(lián)合控制系統(tǒng)設計問題化為以二次型性能指標為目標函數(shù)的干擾抑制的h~線性系統(tǒng)設計問題。
