Robust H-infinity Control of Building Structures with Time Delay

Robust H∞ Control of Building Structures with Time Delay

In this paper, a robust H∞ controller for a building structure with a time delay is studied. Firstly, the motion equation of the structural system with an explicit time delay is introduced. Then, the state space representation of a dynamic equation without any explicit time delay is deduced by a specific integral transformation to the time-delay equation. Secondly, a robust control method is ap...

Robust H∞ Control for Linear Switched Systems with Time Delay

Tracking control of robots using Global H infinity robust control

Recent success in nonlinear H∞ control design has been applied to control of robot manipulator systems. In this paper a Global H∞ robust controller is considered for tracking control problem of Robotic manipulators. The synthesis of this controller is based on Lyapunov function instead of solving the HJI equation. Performance issues of the Global H∞ robust controller are illustrated in a simula...

Robust Time-Delay Control

A method is presented to minimize residual vibration of structures or lightly damped servomechanisms. The method, referred to as the proportional plus multiple delay (PPMD) control, involves the use of multiple time delays in conjunction with a proportional part to cancel the dynamics of the system in a robust fashion. An interesting characteristic of the controller involves addition of a basic...

Robust Stability and H-Infinity Performance Analysis of Interval-Dependent Time-Delay Systems

Robust stability and performance analysis techniques are presented for time-delay systems consisting of the feedback interconnection of a linear time-delay system, with a bounded and casual linear operator. This linear operator features all the parameter and/or dynamical uncertainties excluding the delay elements. The delays considered are noncommensurate, time-invariant but uncertain, residing...
