Robust Controller Design For INDI-Controlled Quadrotor Using Online Parameter Identification
Tom Aantjes, Till M. Blaha, Spilios Theodoulis +1
It has recently been shown that all physical parameters of an Incremental Nonlinear Dynamic Inversion (INDI) controller can be estimated onboard a multirotor within half a second,…
Design and Control of A Tilt-Rotor Tailsitter Aircraft with Pivoting VTOL Capability
Ziqing Ma, Ewoud J. J. Smeur, Guido C. H. E. de Croon
Tailsitter aircraft attract considerable interest due to their capabilities of both agile hover and high speed forward flight. However, traditional tailsitters that use aerodynamic…
Flying a Quadrotor with Unknown Actuators and Sensor Configuration
Till M. Blaha, Ewoud J. J. Smeur, Bart D. W. Remes +1
Though control algorithms for multirotor Unmanned Air Vehicle (UAV) are well understood, the configuration, parameter estimation, and tuning of flight control algorithms takes quit…
Control of Unknown Quadrotors from a Single Throw
Till M. Blaha, Ewoud J. J. Smeur, Bart D. W. Remes
This paper presents a method to recover quadrotor UAV from a throw, when no control parameters are known before the throw. We leverage the availability of high-frequency rotor spee…
