A self-triggered control task is one in which the task determines its next release time. It has been conjectured that self-triggering can relax the requirements on a real-time scheduler while maintaining application (i.e. control system) performance. This paper presents preliminary results supporting that conjecture for a self-triggered real-time system implementing full-information H∞ controll...

Abstract: We present a systematic method to synthesize a decentralized coherent quantum robust H controller for a class of large-scale linear complex quantum stochastic systems with norm-bounded structured uncertainties. The H control objective is to obtain a closed loop uncertain quantum system, which is strict bounded real with a specified disturbance attenuation level. The solution to this q...

In this paper, we study the problem of fault detection in linear time-invariant systems which contain two types of inputs: Inputs with fixed and known spectral densities and inputs with bounded power. It is shown that this problem can be formulated as a mixed H2/H∞ filtering problem where the filter gain is computed by solving a pair of coupled Riccati equations. Alternatively, it is shown that...

There are many control methods of wind power generator set, and various control technology has successful applied cases,however, with the content augment of set, we need to improve dynamic stability. The routine traditional control technology (for example PID control) can’t satisfy the requirements now. Aiming at the particularity of wind power generator set, the paper puts forward a new gain s...

This paper investigates both the H∞ and robust H∞ reduced order unbiased filtering problems for respectively a nominal bilinear system and a bilinear system affected by norm-bounded structured uncertainties in all the system matrices. First, an algebraic framework is used to solve the unbiasedness condition and second, a change of variable is introduced on the inputs of the system to reduce the...

In this paper active suspension with linear electric motor has been designed. The active suspension is often hardly rejected for its big energy consumption. This contribution deals with direct real-time energy control in suspension system. The linear electric motor is used as an actuator. This motor can in specific situation generate the energy for next use. The H-infinity controller has been d...

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...

The proposed article deals with uncertain description of permanent-magnet DC motor Maxon RE 35 via parametric uncertainty and H-infinity controller design. There was analyzed influence of uncertainties of the particular motor parameters on the model behavior. Consequently there was designed an H-infinity controller via Matlab functions. The behavior of the obtained controller was analyzed on th...
