In this paper, a Fault-Tolerant Control
strategy (FTC) was applied using a linear dynamical model of a business jet
aircraft subjected to actuation faults. As a baseline controller, an optimal
linear quadratic tracker was designed to control some selected aircraft
motion variables. Faults due to the loss of effectiveness were assumed. Then,
the FTC was built upon a compensation of faults into the dynamical equations.
The complete system was tested using nonlinear simulations of the aircraft
dynamics. The results demonstrate the ability of the FTC strategy to maintain
the stability of the system and to improve the tracking performance for a
large scope of faults.

State Feedback Optimal Flight Controller
with Tracking Feature
|
|
ملخص المشاركة:
|
This paper is concerned with the design of
a state feedback optimal control system for lateral motion of an aircraft. A
linear quadratic regulator approach was used where set of mathematical
equations was solved for controller gains. The controller incorporated
tracking feature to adjust the dynamic of the aircraft to follow certain
command input. Performance of the developed controlled was analyzed in terms
of rise time, oscillation and settling error. The designed controller was
designed using a linearized model of DC-8 aircraft lateral motion.

Fault
Tolerant Flight Control Design against Actuator Impairments Using Optimal
Control and Fault Compensation
|
|
ملخص المشاركة:
|
This paper presents the design of fault
tolerant flight control (FTC) law to deal with actuators loss of
effectiveness. A Linear Quadratic Regulator (LQR) approach was considered as
a baseline controller augmented with tracking equations to follow command
reference inputs. Fault compensation-based approach was applied to act
against actuator faults. The designed FTC law was examined by analyzing the
aircraft’s motion and the changes in actuators deflections. A mathematical
model of the lateral motion of a DC-8 aircraft was used in this experiment.
Simulation results showed that this technique is very effective to deal with actuator
faults and to maintain the stability of the closed-loop system.
