直流位置伺服系统改进型IMC-PI控制方法

针对直流位置伺服系统,提出了一种改进型IMC-PI控制方法。引入作用函数,并将其与IMC-PI控制器串联,构成改进型PI控制器,其中IMC-PI控制器根据内模控制原理进行设计,作用函数为系统偏差的微分表达式,其阶次的选择应保证系统开环传递函数为严格正则。改进IMC-PI控制可使系统的调节过程分为作用函数趋近零和保持为零的两个阶段,从而保证系统偏差按照作用函数等于零确定的轨迹趋近于零。仿真结果表明所提方法可使系统具有良好的动态响应性能和鲁棒性。另外,利用Qstudio RP实验平台跟随跟随1+sin(10t)rad正弦信号时,IAE为0.14 rad·s,实验结果表明该方法可有效改善伺服系统的性能。     

Can Governments Negotiate With Insurgents? The Latin American Experience

In June 2016, the Colombian Government and the FARC insurgent movement signed a ceasefire agreement, which brings the two sides one step closer to putting an end to over five decades of war. Unfortunately, Latin America has a rich history of insurgent movements, particularly during the cold war era, some of which continue to operate today. Most of these movements disappeared due to military operations, though some did so via peace negotiations. This essay aims to discuss the various ends of Latin American insurgencies to answer whether, indeed, insurgents can be negotiated with.     

Robust cubature Kalman filter method for the nonlinear alignment of SINS

Nonlinear initial alignment is a significant research topic for strapdown inertial navigation system(SINS).Cubature Kalman filter(CKF)is a popular tool for nonlinear initial alignment.Standard CKF assumes that the statics of the observation noise are pre-given before the filtering process.Therefore,any unpredicted outliers in observation noise will decrease the stability of the filter.In view of this problem,improved CKF method with robustness is proposed.Multiple fading factors are introduced to rescale the obser-vation noise covariance.Then the update stage of the filter can be autonomously tuned,and if there are outliers exist in the observations,the update should be less weighted.Under the Gaussian assumption of KF,the Mahalanobis distance of the innovation vector is supposed to be Chi-square distributed.Therefore a judging index based on Chi-square test is designed to detect the noise outliers,determining whether the fading tune are required.The proposed method is applied in the nonlinear alignment of SINS,and vehicle experiment proves the effective of the proposed method.

A nation-in-the-making,in arms: control of force,strategy and the Ukrainian Volunteer Battalions

At the core of waging war and strategy is the creation, control and use of force. This article investigates the volunteer battalions that mobilized in Ukraine during the spring of 2014. It contextualizes the volunteer phenomenon and focuses on the state strategies to establish control over these militias. As ambiguous entities arising from a situation characterized by rapid social change – revolution and war – the volunteer battalions threatened existing hierarchies and questioned state authority. The situation was exacerbated by the war, which deviated from the expectations of Ukrainian combatants and Western military observers alike. The state nevertheless enjoyed a modicum of success in reining in the militias through four strategies of undermining, co-option, incorporation and coercion. While predominantly integrated into a more rigid category of paramilitary forces, the volunteers continue to play a role in both the Ukrainian society and security sector to the unforeseeable future.
