Aimed at the deficiency of existing PID controller for quad rotor UAV, a single neuron with gravity compensation is presented. After using feed forward control to compensate gravity, position loop adopts ensure accuracy, while attitude increase adaptive ability. Then, by Matlab/simulink simulation software, UAV carried out, and result shows, compared traditional double closed controller, algori...

the problem discussed in this paper is the effect of latency time on the ogy chaos control methodology in multi chaotic systems. the smith predictor, rhythmic and memory strategies are embedded in the ogy chaos control method to encounter loop latency. a comparison study is provided and the advantages of the smith predictor approach are clearly evident from the closed loop responses. the comple...

As one of effective regulation methods, static synchronous compensator (STATCOM) has been widespread used to regulate dynamic reactive power and solve dynamic voltage stability problems into powergrid. Through the analysis of mathematical model, cascaded STATCOM, which is constructed by several cascaded H-bridges, is a nonlinear, multivariable, strongly coupled system. It will make difficulties...

This article studies 2-D formation stabilization and maneuvering of mobile agents governed by double-integrator dynamics. The desired is described a set triple-agent interior angles. A carefully chosen such angle constraints guarantees that the rigid. To achieve rigid formation, control law proposed using only local velocity direction measurements. We show closed-loop dynamics when each agent m...
