Robust Sensor Fault Estimation for Control Systems Affected by Friction Force
نویسندگان
چکیده
The paper presents an observer-based estimation of sensor fault for control systems affected by friction force. In such systems, the non-linearity force leads to deteriorating capability observer. Hence, challenge is design observer capable attaining robust while avoiding effects friction. To overcome highlighted challenge, Unknown Input Observer (UIO) designed decouple as well estimate state and fault.The benefit proposing UIO guarantee despite highly non-linear disturbance in form gains are computed through a single–step linear matrix inequality. Finally, inverted pendulum simulation presented demonstrate novel approach's performance effectiveness. Index Terms—Robust estimation, Fault-Tolerant control, unknown input observer, Friction force, estimation/decoupling approach.

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
Robust Hybrid Motion Force Control Algorithm for Robot Manipulators
In this paper we present a robust hybrid motion/force controller for rigid robot manipulators. The main contribution of this paper is that the proposed hybrid control system is able to accomplish motion objectives in free directions and force objectives in constrained directions under parametric uncertainty both in robot dynamics and stiffness constraint constant. Also, the given scheme is prov...
متن کاملEstimation Procedures for Robust Sensor Control
Many robotic sensor estimation problems can characterized in terms of nonlinear measurement systems. These systems are contaminated with noise and may be underdetermined from a single observation. In order to get reliable estimation results, the system must choose views which result in an overdetermined system. This is the sensor control problem. Accurate and reliable sensor control requires an...

The problem of adaptive fault-tolerant control for linear systems with time-varying actuator faults including outage and loss of effectiveness is investigated in this paper. After presenting a time-varying actuator fault model, a novel adaptive observer is designed so that the fault parameter can be estimated fast. Here, the inevitable fault estimation error, as well as the exogenous disturbanc...
