linearized equation meaning in Chinese
线性化方程
Examples
- 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。 - 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，飞机的动态模型具有显著的非线性，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系统设计的要求。这就迫使我们研究飞机的非线性设计方法。 - In chapter 3 , the non - linear equation was linearized with the jacobi matrix , and then the linearized equation was transformed into fixed frame to analyze the stability problem with eigenvalue method ( on - ground or hovering ) or floquet theory ( forward flight ) . meanwhile , the equation was perturbed by sweep frequency excitation from steady state to get transit decay of lag response which was then transformed into fixed frame with a numerical fourier coordination transformation ( fct ) . the fixed frame response along with the body response was analyzed via an fft to determine modal frequencies
然后,在稳态响应的基础上利用雅各比矩阵对非线性方程进行了线化,线化后的方程利用多桨叶坐标变换转换到固定系下后,利用直接特征值分析(地面、悬停)或floquet理论(前飞)对系统进行了稳定性分析;同时,对系统进行了瞬态响应分析;在系统达到稳态的基础上进行扫频激励,用fft变换求得系统频率,进而用移动矩形窗方法分析得到系统的阻尼。
