| 摘 要： | 针对大展弦比这种对侧向着陆精度要求很高的飞机，设计了一种经典PID控制器加预测控制器的分层控制系统。仿真实验结果表明，该控制系统能够有效地提高着陆精度并严格控制接地时的滚转角。

| Abstract: | Present aircraft ALCS (automatic landing control system), usually employing PID control, appears unable to meet the high landing precision required by aircraft with long flexible wings. We propose combining PID control with MPC to make landing precision higher. Section 1 reviews relevant information about MPC in Refs.1 and 2. Subsection 1.1 describes model used in MPC. Subsection 1.2 describes scroll optimization of MPC. Subsection 2.3 compares in much detail simulation results of landing precision of ALCS using PID control alone with those using PID control combined with MPC. Figs.4 through 7 show details of such comparison; significantly higher landing precision is obtained using PID control combined with MPC. Even under lateral wind of 10 m/s during landing, the aircraft bank angle can be controlled not to exceed 2 degrees. |
