对保持飞行速度恒定及保持飞行迎角恒定两种自动动力补偿系统 (Approach powercompensator system,APCS)所构成的飞行 /推力综合控制进行了评估。在此基础上 ,提出了APCS采用控制规则在线自调整及非线性参数优化的模糊逻辑控制。其设计思想是 ,从工程实现考虑 ,在油门控制律中省去法向加速度 Δaz及舵偏 Δδe两路反馈信息。仅根据迎角误差 Δα及其变化率 Δα的大小 ,在线地自调整加权因子 ,以提高稳态控制精度 ,消除由于量化误差而引起的稳态振荡。利用非线性优化控制算法 ,对 APCS模糊控制器参数进行优化设计 ,进一步改善了当代迎角恒定的飞行 /推力综合控制性能 ,并已被仿真所证实 The integrated flight / thrust control of two automatic power compensation systems (APCS) that maintains a constant flight speed and maintains a constant attack angle of attack is evaluated. On this basis, the fuzzy logic control of APCS adopting self-adjusting control rules and nonlinear parameter optimization is proposed. The design idea is that, from the project realization consideration, the accelerator control law eliminates the normal acceleration Δaz and the rudder deviation Δδe two-way feedback information. Only on the basis of the angle of attack error Δα and the rate of change Δα, the weighting factors are adjusted online to improve the steady state control accuracy and eliminate the steady state oscillation caused by the quantization error. The nonlinear optimal control algorithm is used to optimize the parameters of the APCS fuzzy controller to further improve the contemporary flight / thrust control performance with constant attack angle and has been verified by simulation
