The optimization design of aerodynamic shape for reentry vehicles ( asrv ) is a design problem of the complex engineering system , which often involves several subsystems and various parameters 再入飞行器气动布局优化设计是一个复杂的工程系统设计问题,通常包含若干子系统和大量的设计参数。
Next , we explore the programming design in video processing system , and expand it to use design patterns to resolve problems . in the end , the thesis give an integrate design of image processing system , and a relatively integrate reusable framework based on it 在视频处理可复用框架方面,本文从视频处理系统的特点分析入手,对视频处理系统体系结构和模块进行了研究,从解决视频处理系统设计问题出发实现了系统的主要构成,并给出了在相关设计下的框架结构图。
With respect to the issue of integrated flight / propulsion control system design , adopting the decentralized solutions of system integration , this article studied the key technologies in this integrated control system , based on which a real - time integrated closed - loop model of plane / engine was built and a study of variable structure control of integrated flight / pro - pulsion control system was conducted . through a great many simulations , the feasibility of the solution was verified and a simulating platform of integrated flight / propulsion control system was designed and developed by utilizing directx multi - media development libraries 本文针对飞行/推进综合控制系统设计问题,采用分散的系统综合方案,研究了飞行/推进综合控制中的关键技术,在此基础上建立了飞机/发动机综合闭环实时模型,进行了发动机的变结构控制研究,通过大量的仿真,验证了控制方案的可行性,并基于directx多媒体开发库设计完成飞/推综合控制系统仿真平台界面的开发。
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 为了得到船舶舵鳍联合控制系统的状态反馈h ~设计的数学模型,把非线性项及与横荡速度相关的项也看作是对系统的扰动,把非线性船舶舵鳍联合控制系统设计问题化为以二次型性能指标为目标函数的干扰抑制的h ~线性系统设计问题。
