This paper is concerned with sliding-mode boundary control (SMBC) of a vibrating string system under parameter variation. The excited by time-varying distributed disturbance. Dynamics the are described two types differential equations, namely: (a) non-homogenous hyperbolic partial equation (PDE) and (b) ordinary equations (ODEs). In proposed scheme, perturbations damped in presence law based on original infinite dimensional model applied at free end string. Robustness this scheme validated...
In this paper, the dynamics solution problem and boundary control for Timoshenko beam under uncertainties exogenous disturbances are addressed. The of represented by one non-homogenous hyperbolic partial differential equation (PDE), homogenous PDE, three ordinary equations (ODEs). authors suggest a method lines (MOL) obtaining in form ODE formula instead PDE formula. A global sliding mode (GSMBC) is designed vibration reduction influenced uncertainties, distributed disturbance, displacement...
By integrating H∞ control into iterative learning boundary (ILBC) with the method of lines (MOL), this paper suggests a novel scheme to reduce vibrations uncertain vibrating string system in presence iteration-varying distributed/boundary disturbances. The dynamics are defined by two kinds differential equations, namely: (a) non-homogenous hyperbolic partial equation (PDE) and (b) ordinary equations (ODEs). Firstly, MOL is employed attain form state-space instead PDE system. Secondly, ILBC...
Abstract Electrostatic actuators have major role in many MEMS devices, e.g. sensors, actuators. The amount of applied voltage to an electrostatic micro-actuator has a direct impact on the amplitude deflection throughout cantilever. This research aims study effect electrode length and micro-cantilever. Also, resonant frequency for cantilever was computed full compared with simulation results. Finite element method, ANSYS used as tool.
