多数实际物理系统都具有某种程度的非线性,因此需要寻求有关非线性系统简便有效的解法。本文的目的是说明如何通过对近似线性模型的研究,来实现非线性系统特性的区域划分,并着重说明对二阶模型开关控制问题的计算和实际应用。
Most physical systems have some degree of nonlinearity, so simple and effective solutions to nonlinear systems are needed. The purpose of this paper is to show how to partition the nonlinear system characteristics by researching the approximate linear model and to emphasize the calculation and practical application of the second-order model switch control problem.
