Abstract [en]

Aircraft control allocation deals with the problem of distributing a given aerodynamic moment demand among an available, redundant set of control surfaces. Most existing methods for control allocation are static in the sense that resulting control distribution only depends on the current moment demand. In this paper we propose a method for dynamic control allocation, in which the relationship between the moment demand and the resulting control distribution is dynamic. In the non saturated case, the resulting control distribution is determined by a first order linear filter which can be assigned different properties at different frequencies. The main advantage of the method is that it allows the user to design the transient and steady state control distributions separately. The control allocation problem is posed as a constrained quadratic programming problem which allows for automatic redistribution of the control effort when one actuator saturates in position or in rate.
