A vehicle includes a system performing a method of controlling an operation of the vehicle during a tire blowout. The system includes a vehicle dynamics sensor for detecting a dynamic parameter of the vehicle, tire sensors for detecting wheel speeds of wheels of the vehicle, and a processor. The processor is configured to receive a velocity of the vehicle from the vehicle dynamics sensor and the wheel speeds from the tire sensors, determine a diagonal product ratio of the wheel speeds, compare the diagonal product ratio to a range to detect an occurrence of a tire blowout, identify a location of the tire blowout from a wheel speed ratio based on wheels that are diagonally opposite each other, and control the operation of the vehicle in response to the tire blowout.

A transformable Unmanned Aerial Vehicle (UAV), can operate as a coplanar hexacopter or as an omnidirectional multirotor based on different operation modes. The UAV has 100% force efficiency for launching or landing tasks in the coplanar mode. In the omnidirectional mode, the UAV is fully actuated in the air for agile mobility in six degrees of freedom (DOFs). Models and control design are developed to characterize the motion of the transformable UAV. Simulation results are presented to validate the transformable UAV design and the enhanced UAV performance, compared with a fixed structure.
