A design of an optimal backstepping fractional order proportional integral derivative (FOPID) controller for handling the trajectory tracking problem wheeled mobile robots (WMR) is examined in this study. Tuning parameters a challenging task, to overcome issue hybrid meta-heuristic optimization algorithm has been utilized. This evolutionary technique known as whale grey wolf optimizer (HWGO), w...

This work proposes a systematic methodology for the optimal selection of controller parameters, in the sense of minimizing a performance index which is a quadratic function of the tracking error and the control effort. The performance index is calculated explicitly as an algebraic function of the controller parameters by solving a Zubov-type partial differential equation. Standard nonlinear pro...

This paper discusses energy extraction from atmospheric turbulence by smalland microuninhabited aerial vehicles. A controller which superimposes a gust-dependent control input on a state-feedback derived control input is proposed, and a genetic algorithm is used to obtain control gains as well as the optimal nominal trim state is described. Control laws are designed for both vertical sinusoidal...

Nuclear power reactors are, in nature nonlinear and time varying. These characteristics must be considered, if large power variations occur in their working regime. In this paper a robust optimal gain scheduling controller for regulating the power of a nuclear reactor has been designed and simulated. The proposed controller is capable of regulating power levels in a wide power range (10% to 100...

In this paper, we apply a multiple controller based adaptive method to solve a tracking problem, where the plant output is required to track a reference input. The proposed methodology is based on an unfalsification approach. The method relies on a finite set of candidate–controllers; depending on the evolving plant data, it learns and selects an optimal controller from the candidate controller...

This paper describes the robust optimal incremental motion control of a current  sensorless synchronous reluctance motor (SynRM), which can be specified by any desired speed profile. The control scheme is a combination of conventional linear quadratic (LQ) feedback control method and sliding mode control (SMC). A novel sliding switching surface is employed first, that makes the states of the Sy...
