【摘要】：為提高水翼艇縱向運動控制的魯棒性和節(jié)能效果,在保持已有的多輸入多輸出(Multiple-Input Multipe-Output,MIMO)魯棒控制器不變的基礎上,引入正弦函數(shù)驅動的非線性反饋代替原有的誤差線性反饋。仿真結果表明:在模型攝動時,魯棒控制器主要改進縱搖效果,而非線性反饋控制能同時改進升沉和縱搖效果,控制效果比魯棒控制器提升70%以上,控制能量比魯棒控制器節(jié)省90%以上。簡單的理論分析和仿真研究結果表明:正弦函數(shù)驅動的非線性反饋對于MIMO系統(tǒng)的控制同樣適用。
[Abstract]:In order to improve the robustness and energy efficiency of hydrofoil longitudinal motion control, the sinusoidal nonlinear feedback is introduced to replace the original error linear feedback on the basis of keeping the existing Multiple-Input Multipe-Output MIMO robust controller unchanged. The simulation results show that the robust controller mainly improves the pitching effect when the model is perturbed, while the nonlinear feedback control can improve both heave and pitch effects, and the control effect is more than 70% higher than that of the robust controller. The control energy is more than 90% less than the robust controller. The simple theoretical analysis and simulation results show that the sinusoidal function driven nonlinear feedback is also applicable to the control of MIMO systems.
