Furthermore, we compute the Riemann solution by using a bisection method combined with the phase-planeanalysis.
进一步地，我们采用二分法与相平面分析结合的方法计算压差方程的数值解。
2
The first one is about how to build the connection between describing function method and phaseplane method through limit cycle analysis.
第一个是关于如何通过极限环分析建立描述函数法与相平面法之间联系；
3
The second one is about how to enhance the connection between system compensation and phaseplaneanalysis method through introducing PID parameter self-tuning method based on relay.
