This paper presents a gain-scheduled approach for boiler-turbine controller design. The objective of this controller design is to achieve tracking performance in the power output and drum pressure while regulating water level deviation. Also, the controller needs to take into account the magnitude and rate saturation constraints on actuators. The nonlinear(More)
The present paper investigates the problem of robustly decentralized H state feedback controller with state variance constraint design for a class of stochastic large-scale uncertain time-delay systems. The considered time-delay parameters appear in the interconnections between individual subsystems and uncertainties are allowed to be unstructured but(More)
The purpose of the paper is to develop a PEM fuel cell power system with application for the electric bike. The output voltage of the fuel cell subjects to change due to load varying and polarization loss. By applying the energy conversion method with pulse-width modulation and MOSFET switching with proper frequency and duty cycle, the issues of power(More)
This paper is on the study of a single wheel device which can be driven by both human and electric power. The conventional unicycle via human power only is usually for sports or performs, seldom used for transportation. The riders need training/practice and good balancing for successful manipulation. The difficulty is on the longitudinal balancing during(More)
This paper investigates multi-objective controller design approaches for nonlinear boiler-turbine dynamics subject to actuator magnitude and rate constraints. System nonlinearity is handled by a suitable linear parameter varying system representation with drum pressure as the system varying parameter. Variation of the drum pressure is represented by(More)
In this paper, we design a multi-objective controller ( ) u t to achieve the following three objectives simultaneously. They are pole placement, H∞ norm constraint and individual error state variance constraint for stochastic model reference systems. By using the invariance property of sliding mode control, the matched model reference input and the plant(More)
The proposed controller design algorithm in this paper can take into account independently both the magnitude and rate constraints on actuator dynamics. The control law is constructed in terms of linear matrix inequalities. A suitable chosen initial state condition, which can represent the desired set of tracking commands, is treated as a parameter for the(More)
