Graduate studies in fields of Engineering typically include advanced control theory. In turn, these courses enhance both academic and applied research, hence contributing to combined knowledge and technology transfer, in particular if supported by industry as well. This paper reports on such fruitful experiences at our universities through the math-analytical back-stepping and state-feedback co...

Abstract: In this study, the altitude control is analyzed for the longitudinal dynamics of a generic Hypersonic Flight Vehicle (HFV). By transforming altitude command into the tracking of flight path angle with fast dynamics, the system design is focusing on the control of the attitude subsystem. The virtual control is designed with nominal feedback and Neural Network (NN) approximation via bac...

A new control methodology is introduced for nonlinear, MIMO Heating, Ventilating and Air Conditioning (HVAC) Systems. A feedback of states and disturbances is used for disturbance decoupling and model linearization purposes. The Back-stepping controller is applied to the system’s linearized model, then. It is shown that in this way, heat and moisture loads can be compensated completely if consi...

In this paper, the problems of control and stabilization of switched nonlinear cascade systems is investigated. The so called simultaneous domination limitation (SDL) is introduced in previous works to assure the existence of a common quadratic Lyapunov function (CQLF) for switched nonlinear cascade systems. According to this idea, if all subsystems of a switched system satisfy the SDL, a CQLF ...

Abstract: This study proposes a feedback linearisation based on the back-stepping method with simple implementation and unique design process to design a non-linear controller with a goal of improving both steady-state and transient stability. The proposed method is designed based on a standard third-order model of synchronous generator. A comparison based on simulation is then performed betwee...

AIM This study aimed to examine sex and age differences of various stepping movements in the elderly and to clarify useful stepping movements for evaluation of their dynamic balance. METHODS Two hundred and eighty-six healthy elderly subjects who could walk independently (male mean age = 71.2 +/- 7.1 years; female mean age = 71.5 +/- 6.0) performed the following stepping tests: back and forth...

This paper presents an on-line nonlinear trajectory tracking control algorithm for differential wheeled mobile robot using optimal back-stepping technique based particle swarm optimization while following a pre-defined continuous path. The aim of the proposed feedback nonlinear kinematic controller is to find the optimal velocity control action for the real mobile robot. The particle swarm opti...
