An optimal control problem with linear dynamics and convex but not necessarily quadratic and possibly infinite-valued or nonsmooth costs can be analyzed in an appropriately formulated duality framework. The paper presents key elements of such a framework, including a construction of a dual optimal control problem, optimality conditions in open loop and feedback forms, and a relationship between...

In this paper, distributed parameter process systems behavior is studied in frequency domain. Based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. By using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...

Closed loop neuromodulation, where the stimulation is controlled autonomously based on physiological events, has been more effective than open loop techniques. In the few existing closed loop implementations which have a feedback, indirect non-neurophysiological biomarkers have been typically used (e.g. heart rate, stomach distension). Although these biomarkers enable automatic initiation of ne...

Abstract I The purpose of this paper is to propose a fast adaptive terminal sliding mode control method for quadrotor unmanned aerial vehicles (UAVs) under dynamic uncertainties and external interference. Firstly, complete mathematical dynamics model UAV presented. Secondly, robust dual-loop nonlinear law the velocity attitude tracking designed. Through introduction equivalent inputs, channels ...

Abstract In this paper, the dual closed-loop control strategy with fractional-order PI is applied to field of DC-DC converter, which effectively improves dynamic performance and static output voltage power electronic DC chopper converter. The open-loop transfer function Boost converter obtained by modeling analyzing operating principle small-signal model parameters double are combining frequenc...
