Integrated Design of Structural and Semi-active Control Systems: Inverse Lyapunov Approach

Optimal integrated passive/active design of the suspension system using iteration on the Lyapunov equations

In this paper, an iterative technique is proposed to solve linear integrated active/passive design problems. The optimality of active and passive parts leads to the nonlinear algebraic Riccati equation due to the active parameters and some associated additional Lyapunov equations due to the passive parameters. Rather than the solution of the nonlinear algebraic Riccati equation, it is proposed ...

An optimal semi-active thermal exchange-Fuzzy logic Controller for Structural Dynamic Control and Rehabilation

The effect of intelligent semi-active thermal exchange-fuzzy controller in structural rehabilitation by attenuating seismic responses of structural systems is investigated. In the suggested control system, MR dampers and sensors are employed as a semi-active controller. Resultant control forces of MR damper are administrated by providing external voltage supply, during the earthquakes and high ...

Design of Active Structural Acoustic Control Systems Using Eigenassignment Approaches

(ABSTRACT) Active structural acoustic control (ASAC) in conjunction with the adaptive feedforward control has been proved to be an efficient practical approach to reduce structure-borne sound. ASAC works on the principles of reducing the vibration amplitude of the structure (modal reduction), as well as changing the vibration distributions of the structure so that the vibration distributions of...

Discrete-time control design with positive semi-definite Lyapunov functions

A useful stability analysis technique from continuous-time nonlinear systems [2] is extended to the discrete-time domain. The result is illustrated on a practical example.
