非线性恢复力 meaning in Chinese

nonlinear restoring force

For a class of linear systems or the systems containing a nonlinear recovering force , it is discussed how to make them become chaotic systems by adding a nonlinear feedback unit , and the parameters estimation method of the system is introduced
在系统参数估计的应用方面，讨论了对于一类线性的或含有非线性恢复力的系统，如何通过加入非线性反馈环节使其处于混沌态。然后介绍了这种混沌系统的参数估计的符号动力学方法。
