A recently reported solution for stationary stability of a thermosolutal system with Soret diffusion is re-derived and examined using a symbolic computational package. Symbolic computational languages are well suited for such an analysis and facilitate a pragmatic approach that is adaptable to similar problems. Linearization of the equations, normal mode analysis, and extraction of the final so...

In this paper, an adaptive fault-tolerant control scheme is extended to large-scale interconnected systems with actuator failures and external disturbances. Based on Lyapunov stability theory, a state feedback decentralized controller is designed to compensate for the fault and the disturbance effects, using the overlapping decomposition method. Applying the inclusion principle, the interconnec...

The use of a super-capacitor as storage device integrated with Voltage source converter-based shunt-connected Static Synchronous Compensator (STATCOM) is proposed for improving the STATCOM performance during sudden large disturbances in power network. was applied across capacitor disturbance condition. MATLAB simulations were carried out verification secondary function like oscillation damping,...

Research on biped humanoid robots is currently one of the most exciting topics in the field of robotics and there are many ongoing projects. Because the walking of humanoid robot is complex dynamics inverse problem the pattern generation and dynamic simulation are extensive discussed. Many different models are proposed to simple the calculation. Many researches about the walking stability and p...

This paper proposes a high gain disturbance observer based control approach for nonlinear systems. Compared with previous works, it can admit a much larger class of disturbances produced by nonlinear exo‐systems. Our approach will follow the framework of the two‐stage design procedure, which separates the disturbance observer design from the controller desi...

Saturation nonlinearities caused by control limiters will be activated during large disturbances, complicating the stability of grid-tied voltage source converters (VSCs). This letter investigates large-disturbance synchronization VSC considering two typical limiters, i.e., hard limiter reference current and circular used to avoid overmodulation. A unified differential equation (UDE) model is p...

Recent works have combined tools from graph theory and control theory to derive stability criteria for vehicle formations. The formulation typically models information exchange between vehicles in a formation by using graph-theoretic tools. This work builds upon these ideas by studying the link between topology of these graphs and the dynamical behavior of a formation subject to disturbances. T...
