Abstract
Official abstract text for this publication.
A vehicle control system and method combining control allocation and phase compensation for forming a phase compensated actuator command signal based on a control demand signal. A feedback unit includes a matrix multiplication unit for forming an estimated behavior signal, from a control efficiency matrix and the actuator command signal. The estimated behavior signal is fed to a second summation unit for forming a difference signal. The difference signal is processed by a filter unit for forming a feedback signal which is connected to a first summation unit for forming a modified control demand signal, such that the modified control demand signal is adjusted to always represent a control demand realizable by the vehicle. The modified control demand signal is further connected to the second summation unit and to a control allocator which output is then connected to the matrix multiplier to form a feedback loop.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle control system for a vehicle, comprising: control elements configured to alter at least one of a speed, altitude or course of a vehicle; an input actuator configured to be actuated by an operator to input control demand; a control allocator configured to allocate a received control demand by providing actuator control signals derived from said control demand to a plurality of actuators for the control elements; a feedback module compris…
