small disturbance theory meaning in English

小扰动理论

As the complexity of flight tasks increases , the linearized equation based on the small disturbance theory is no longer adequate for the design of control systems , and the necessity of exploring a nonlinear approach seems increasingly obvious
随着飞机飞行任务不断趋向复杂化，基于小扰动线性化方程的线性系统设计方法已经难以满足现代飞机飞控系统的设计要求。这就迫使我们研究飞机的非线性控制律的设计方法。
