A vertical take-off and landing aircraft that includes AC motors, which drive fans that propel the aircraft, and a control device for controlling the AC motors adaptively based on a thrust control amount from an attitude controller. In particular, the drive controller performs switching to convert DC from a power source to three-phase AC at a predetermined frequency to be supplied to the AC motors. The drive controller reduces the control frequency of the three-phase AC to be applied to the AC motor to reduce the control resolution when the flight mode i...
What is claimed is: 1. A vertical take-off and landing aircraft comprising:a fan for propelling the vertical take-off and landing aircraft;a driving device for electrically driving the fan; anda control device for controlling the driving device adaptively to an external force, wherein:the control device reduces a control resolution of a control amount that is applied to the driving device as the control amount to correct the external force decreases;the control device reduces the control resolution of the control amount that is applied to the driving dev...
