To avoid collision with static and dynamic obstacles , the magnitude and direction of the acceleration of mobile robot was adjusted dynamically in real time based on the relative acceleration information 相對(duì)坐標(biāo)系中,采用包含相對(duì)加速度信息的避碰算法,通過(guò)動(dòng)態(tài)實(shí)時(shí)地調(diào)整機(jī)器人加速度的大小和方向,使其避開(kāi)障礙物。
To make the control system feasible and easy to operate , a new scheme is put forward . the acceleration information of the top deck motion is used as input data and an empirical formula is used to obtain the optimum parameters of the vstmd 此方法在不降低控制器效果的前提下簡(jiǎn)化了優(yōu)化程序,提高了運(yùn)算速度,更有利于平臺(tái)振動(dòng)的實(shí)時(shí)控制,實(shí)現(xiàn)控制系統(tǒng)對(duì)結(jié)構(gòu)振動(dòng)的最優(yōu)控制。
Backed up by the soplat theory based on particle kinematics , the second chapter of this paper presents with analysis and simulation of several single observer passive measurement models , which uses such relative movement parameters as bearings changing rates and centrifugal acceleration information on the basis of bearings measurements . in the third chapter , the observability of location respectively using bearings and its changing rates information and centrifugal acceleration information is analyzed , and its observable condition is got . the fourth chapter puts forward the modified covariance extended kalman filtering ( mvekf ) against the defect of traditional extended kalman filtering ( ekf ) , whose performance is simultaneously compared in the chapter with the performance of ususal tracking algorithm such as ekf , mgekf , iekf by computer simulation 在近年來(lái)提出的基于質(zhì)點(diǎn)運(yùn)動(dòng)學(xué)原理的單站無(wú)源定位理論基礎(chǔ)上,本文第二章提出了幾種在角度測(cè)量的基礎(chǔ)上增加角度變化率及相對(duì)運(yùn)動(dòng)的離心加速度等運(yùn)動(dòng)學(xué)參數(shù)的單站無(wú)源測(cè)量模型,并對(duì)它們進(jìn)行了分析和仿真;第三章分別對(duì)利用角度及其變化率信息定位和利用離心加速度信息定位的可觀測(cè)性進(jìn)行分析并得到了相應(yīng)的可觀測(cè)條件;第四章針對(duì)傳統(tǒng)擴(kuò)展卡爾曼( ekf )方法的缺點(diǎn),提出了一種修正協(xié)方差的擴(kuò)展卡爾曼濾波( mvefk )方法,并將其和ekf 、 mgekf 、 iekf等常用的單站無(wú)源定位濾波方法進(jìn)行了性能仿真比較;第五章通過(guò)引入雷達(dá)機(jī)動(dòng)目標(biāo)跟蹤方法和模型,提出了利用角度及其變化率對(duì)機(jī)動(dòng)輻射源跟蹤的多級(jí)噪聲自適應(yīng)方法和imm方法;第六章主要對(duì)角度變化率和離心加速度參數(shù)的獲取技術(shù)進(jìn)行了研究,提出了幾種高精度測(cè)量脈沖序列多普勒頻率變化率的方法。
