This article presents an application of the first order sliding mode control in order to damp the mechanical vibrations of a flexible one-link manipulator using piezoceramic actuators. The flexible manipulator, seen as a multiple inputs multiple outputs system is decoupled using state feedback scheme. The model of the system is deduced using the finite element method, and its response to a cont...

The thin-disc piezoceramic-driving ultrasonic actuator dedicated to a stepping ultrasonic motor is proposed. The mechanical hysteresis and dead-zone phenomena are automatically compensated by a closed loop servo control, i.e. Fuzzy Sliding-Mode Control (FSMC), for position tracking. The controller design of FSMC has syncretized the fuzzy reasoning and sliding mode control with robust stability ...

Possibilities for the " parasitic " collection of power from human walking motion are explored. The focus is on the walking action as a source of power because of the extensive range of motion and large dynamic forces associated with the heel strike and the bending of the sole. Two piezoelectric systems: a multilayer laminate made from PVDF foil and a unimorph piezoceramic composite (PZT); as w...

А new closed-loop solution for the coupled nonstationary problem of thermoelectric elasticity is designed a long piezoceramic radially polarized cylinder. The case load acting on its inner cylindrical surface considered as function temperature change at given law convection heat exchange outer face wall (boundary conditions conductivity 1st and 3rd types). Electrodynamic cylinder surfaces are c...
