Abstract:
This paper presents a trajectory planner and a control architecture capable of guiding a quadrotor biplane tailsitter (QRBP) through obstacle cluttered environments. The trajectory planner is formulated as an optimization problem that uses a differentially flat, point-mass model of a QRBP that considers wake effects on the aerodynamic forces generated during transition. Obstacle avoidance is realized as a state constraint in the optimization problem that defines 'no-flight zones' or regions where the QRBP cannot enter based on obstacle size and safety clearance requirements. The 6DOFcontrol architecture is designed as a set of cascaded dynamic inversion controllers that use the aerodynamic feedforward signals produced by the trajectory planner to complete the inversion in the outer loop. To show the effectiveness of the obstacle avoidance path planning methodology, time-optimal trajectories are generated for two f light missions (the hover to forward flight and vice versa) through cluttered environments. The control architecture is validated on these two cases using a high fidelity flight dynamics simulation of a QRBP. The computational efficiency of the trajectory planner and the tracking performance of the control architecture are then empirically validated.
