Due to multicopters' role in advanced air mobility, there has been an increasing interest in handling qualities. This research investigates the effect of control allocation of multicopters on handling qualities. Typically, multicopter aircraft are trimmed with equal speed on each rotor. The force generated by each rotor can be modeled, where thrust T and torque Q of the ith rotor are related to the square of the rotor speed. The dynamic equations indicate that trimming motor pairs at different RPM results in an increase of control effectiveness in the associated axis, improving bandwidth and disturbance rejection. A tradeoff occurs where power usage is no longer optimized, but handling qualities are improved in that control axis. RMAC is a nonlinear blade element model used to evaluate the effects of alternate allocation. An example of an off-nominal mixer for a hexacopter would be to allow higher allocation to the rolling motors (left and right motors). As data from RMAC indicates, this results in higher trim RPM on rolling motors, and lower RPM on pitching motors. System identification flight tests were used to validate the RMAC results. System ID data showed lowering control to the rolling motors gives reduced roll control effectiveness. The rolling motors at high allocation yields similar magnitude at high frequency, but better damping and shifted frequency of the lateral unstable phugoid-like mode at hover, producing a faster and more desirable response. Promising results in increasing handling qualities through off-nominal mixing configurations are shown and validated with flight testing.
