This invention discloses a motor redundancy
control system suitable for manned electric helicopters. The
system includes: a
current sensor, a three-phase
voltage sensor, a motor
position sensor, an inverse converter module, a
motor control algorithm module, a current fault diagnosis and reconstruction module, a Clarke
voltage inverter module, a speed and position monitoring module, and a position / speed
signal fault diagnosis and reconstruction module. Applying this
system ensures the
flight safety of manned electric helicopters, preventing crashes due to
power loss. This
control system primarily addresses the current and position sensors, which are prone to failure during
cruise in manned electric helicopters. Different redundancy control methods are proposed for each. When current and position sensors malfunction, the
system can quickly diagnose the fault and reconstruct the position and current information using position and current reconstruction methods respectively. The fault information is then uploaded to the flight assistance display and
control system to alert the
pilot, allowing for an emergency landing at a suitable location, thus ensuring the stable operation of the manned electric helicopter's
motor control system.
