In this paper incremental nonlinear dynamic inversion, a sensor based approximate form of feedback linearization with favorable robustness properties, is applied to the traction control and stability augmentation problem of a Le Mans Prototype 1 race car. A cascaded side-slip and yaw-rate envelope protection system is developed in combination...

Current flight control systems fail to recover to safe flight conditions in off-nominal flight conditions and require a more advanced upset recovery methodology which is able to provide full control authority. Existing upset recovery methods are focused on fast recovery taking into account the current flight conditions while neglecting nonlinear...

This work presents a vector field based path following method to be used by Multirotor Unmanned Aerial Vehicles (UAVs). The desired path to be followed is a smooth planar path defined in its implicit form. The vector field around the desired path is then constructed using the implicit function, such that the integral curves of the vector field...

Tailless flapping wing micro air vehicles (FWMAVs) have
the potential of providing efficient flight at small scale,
with considerable agility. However, this agility also brings
significant control challenges, which are exacerbated by
the fact that the aerodynamics and dynamics of flapping
wing robots are still only partly...

To solve the problem of optimal control for nonlinear system, Actor Critic Designs (ACD) can be utilized which use the concept of Reinforcement learning (RL) and function approximators such as Neural networks (NN). Traditional ACD methods require a model NN that needs to be trained offline. Recently, research focus has been shifted to model-free...

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...

In the near future many tasks could be performed by swarms of flying robots. To successfully implement multiple of these swarms in the same airspace they will have to be decentralised, autonomously cope with high densities and even resolve conflicting objectives of other swarms, while remaining controllable by operators through high-level...

L1 adaptive control is a relatively new technique that attempts to tackle the robustness shortcoming of the MRAC controller by applying a low pass filter to the control input. It can be used as an augmentation loop using baseline controllers such as backstepping or PID. This controller has been implemented as an augmentation loop with both these...
