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 baseline controllers in three models: a quadcopter, a hexacopter and a Bolkow Bo-105 helicopter 3 degree of freedom model. It is then compared to the baseline where it's shown that this implementation does not provide any significant advantages over the baseline controllers.
