Vibration control of adaptive structure using composite laminated piezoelectric element;

The Deformable Adaptive Structure is a new type of adaptive structure,into which sme sensors and actuators are integrated,with de formation measured by the sensors and the actuators,then ordered to act according to a sPecific control algorithm,so as to make the expected deformation.

This method can improve the working status of adaptive structures and enhance their load capacity.

The active vibration control of adaptive structures for large complex spacecrafts is studied by Human-Simulated Intelligent Control(HSIC) experiments of a tetragonal prism truss with a test platform based on MATLAB/dSPACE environment.

The model free controller is a structure adaptive controller, which is a product of the approach of modeling and control unity and the concepts of PID and linear frame.

Applying the concept of the generalized interception spot, based on the variable structure adaptive theory and choosing the relative velocity deflection angle as the sliding-mode, a variable structure adaptive midcourse guidance law was designed.

A technology of composite control of linear/adaptive variable structure control is briefly introduced,a new kind of switch function is proposed in this paper.

An adaptive variable structure controller for a class of nonlinear chaotic systems is proposed in this paper.

In view of the influence of servo performance for permanent magnet linear synchronous motors(PMLSM)drive system with parameter variations and external force disturbance,the project of adaptive variable structure direct thrust speed control was proposed.
