Nonlinear Flight Control: Fault Tolerant Control with Sliding Modes and Control Allocation

Nonlinear Dynamic Inversion (NDI) is a promising method for Fault Tolerant Flight Control. The NDI algorithm cancels out the aircraft dynamics based on a dynamic aircraft model such that the closed loop system behaves linearly. The aircraft model is estimated online, which allows it to accommodate changes in the aircraft configurations and...

Minimum drag control allocation for the Innovative Control Effector aircraft: Optimal use of control redundancy on modern fighters

The Innovative Control Effector model is a tailless delta-wing aircraft concept equipped with 11 control surfaces with overlapping functionality and two-directional thrust vectoring. The high level of redundancy makes it an interesting object for research on mission-specific control allocation. A (spline-based) incremental control allocation...

Load-sensing Based Integrated Chassis Control: Using hierarchical strategy and control allocation

Evolution of new technologies, market preferences and vehicle safety standards and regulations motivate the automotive industry to contribute to higher quality mobility and safer transportation for the society. With the compelling development of electronics over the past few decades, passenger cars are equipped with an increasing number of...

Extended Incremental Non-linear Control Allocation on the TU Delft Quadplane

This research presents an implementation of a novel controller design on an overactuated hybrid Unmanned Aerial Vehicle (UAV). This platform is a hybrid between a conventional quadcopter and a fixed-wing aircraft. Its inner loop is controlled by an existing but modified control method called Incremental Non-linear Control Allocation or INCA....

Vehicle Dynamics Control Using Control Allocation

Advancement of the state of the art of automotive technologies is a continuous process. It is essential for automotive engineers to combine the knowledge of vehicle dynamics and control theory to develop useful applications that meet requirements of improved safety, comfort and performance. A road vehicle is equipped with several actuators that...

Computationally Efficient Control Allocation Using Active-Set Algorithms

An effective distribution of flight control commands over many aircraft actuators (engines, control surfaces, flaps, etc.) can be achieved with constrained optimisation. Active-Set methods solve these problems efficiently, but their computational time requirements are still prohibitive for aircraft with many actuators or slower digital flight...

Nonlinear Control Allocation for a High-Performance Tailless Aircraft with Innovative Control Effectors: An Incremental Robust Approach

Conventional linear control allocation (LCA) methods fail to provide satisfactory performance in flight control systems (FCS) for aircraft with highly nonlinear and coupled control effector suites, especially for tailless aircraft with strong interactions between control effectors. This thesis implements an incremental nonlinear control...
