A backlash identification and compensation method for high-speed aircraft angular rate control
نویسندگان
چکیده
Abstract This paper focus on the hysteresis phenomenon of roll angular rate control resulting from backlash actuators for a high-speed aircraft in real flight. First, is analyzed time and frequency domain, then parameters are identified using statistic method. Second, based inverse model, L 1 adaptive controller with compensation designed. Third, two simulation tests without conducted results compared which show effectiveness backlash-compensation-based controller.

A New Method for Time-Delay Compensation in Control Systems
In this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. The concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (Ir-TF), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. Ir-TFs, which are we...
متن کاملBacklash Compensation Using Receding Horizon Control
We present a receding horizon control algorithm for compensation of backlash at the input of a stable linear system under control rate constraints. The problem is first posed as a receding horizon optimal control problem by modelling backlash as a piecewise affine system with a state space partition consisting of three regions. This optimal control problem involves solving, at each step, 3 quad...
متن کاملBacklash compensation for plants with saturating actuators
A compensation scheme is proposed for plants subject to both saturation and backlash in series at the actuator. It is shown that the series connection of a backlash inverse, saturation and the backlash itself is equivalent to a saturation function at a different level to the original saturation; we call this the ‘saturation equivalence’. Therefore it is proposed to include such a backlash inver...

متن کاملpresenting a new method for high speed incremental forming
recently, incremental sheet metal forming (ismf) process as one of the new methods in rapid prototyping collection has been considered by researchers. this process is based on a defined path in cnc controller and applies a spherical-head tool that supplies the required pressure for sheet metal forming. despite affirmation of process ability in forming symmetric geometries, some of its aspects s...
