This paper presents a robust passivity-based control (RPBC) strategy for half-wave zero-voltage switching quasi-resonant (HW-ZVS-QR) buck and boost type converters. The proposed controller is based on energy shaping damping injection. Theoretical analysis shows that the resulted closed-loop HW-ZVS-QRs are globally asymptotically stabilised even if physical constraint magnitude of signal taken i...

This article deals with the robust stability analysis and passivity of uncertain discrete-time TakagiSugeno (T-S) fuzzy systems with time delays. The T-S fuzzy model with parametric uncertainties can approximate nonlinear uncertain systems at any precision. A sufficient condition on the existence of robust passive controller is established based on the Lyapunov stability theory. With the help o...

in this study, a new servo control system is presented for the overhead crane based on discrete-time state feedback approach. it provides both robust tracking and load swing suppression. inspired from independent joint and computed torque control in robot manipulator field, a new model is derived in which the crane actuators are considered as the main plant. the crane nonlinearities are then tr...

Real-time hybrid testing involves the separation of a system into an experimental component and numerically simulated substructure which are coupled run together. The coupling between substructures is achieved using actuators force sensors comprise transfer system. Close synchronization required for reliable testing. However, actuator lag may cause tracking errors instability in tests. Existing...

Torque ripple minimization of switched reluctance motor drives is a major subject based on these drives’ extensive use in the industry. In this paper, by using a well-known cascaded torque control structure and taking the machine physical structure characteristics into account, the proposed energy-based (passivity-based) adaptive sliding algorithm derived from the view point of energy dissipati...

This paper examines how to best be with women during birth, based on a phenomenological description of the birth experience. The first part of the paper establishes birth as an uncanny experience, that is, an experience that is not only entirely unfamiliar, but even unimaginable. The way in which birth happens under unknowable circumstances (in terms of when, how, with whom…) creates a set of a...

We reinterprete and improve recent results on robust control of robots by the computed method. The methods and ideas used are inspired by 'passivity based' control methods for robot manipulators and lead to a significant increase in freedom of controller implementation, thereby providing more flexibility to the designer of robot control systems.
