Tracking and Shape Control of a Micro-cantilever using Electrostatic Actuation
نویسندگان
چکیده مقاله:
In this paper the problems of state estimation, tracking control and shape control in a micro-cantilever beam with nonlinear electrostatic actuation are investigated. The system’s partial differential equation of motion is converted into a set of ordinary differential equations by projection method. Observabillity of the system is proven and a state estimation system is designed using extended Kalman filter (EKF) algorithm. A tracking control system is designed to make a specific point of the beam follow a reference signal. The effect of mode selection to include in model on controller performance is also investigated. Based on the tracking controller a shape control algorithm is designed to form the shape of beam into a desired shape. The proposed algorithms are validated by numerical simulation and resulted in a promising performance.

متن کاملNonlinear static and dynamic behaviors of a microresonator under discontinuous electrostatic actuation
This article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. The electrostatic actuation was induced by applying AC-DC voltage between the microbeam and electrode plate. In contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. In additio...

In order to exhaustively exploit the high-level capabilities of shape memory alloys (SMAs), they must be applied in control systems applications. However, because of their hysteretic inherent, dilatory response, and nonlinear behavior, scientists are thwarted in their attempt to design controllers for actuators of such kind. The current study aims at developing a micro-position control system ...

This paper describes the design of a prototype gastro-intestinal intervention system based on an inchworm-type of mobile robot. This type of device is a kind of vehicle for inspection through the colon, something that is currently impossible due to the large number of turns in the intestinal system. Eventually, tools for intervention can be added in the future. The overall system is about 95 mm...
