Simulation results show that the performance of the open-loop control system is poor when the model parameters change. The second system is designed via feedback linearization method. Since the path signal is introduced as feedback signal, the designed closed-loop control system improves the system robustness to the parameter perturbation. Simulation results verify that the closed-loop control system shows better performance than the time optimal control system.

前者侧重于时间最短的控制性能，但由于是开环控制，当出现参数摄动时，系统的性能会受到较大影响；后者由于引入了飞艇轨迹的反馈信号，因而相对提高了系统对参数摄动的鲁棒性，计算量较小，并且仿真结果证实了这种闭环系统设计方案可以抑制参数摄动带来的影响，与时间最优开环控制系统相比，显著提高了控制精度、改善了控制效果。
