| 摘 要： | 线性系统动态仿真的键合图法已经较完善地建立起来。但是对非线性系统应用键合图法进行动态仿真尚有许多工作要做,这不仅由于其系统状态方程的建立比较复杂,而且其解法也比较复杂。本文在考虑到混合因果关系的情况下,推出了非线性多流口系统状态方程的统一表达式,并采用有限差分同Broyden的拟牛顿法相结合来求解。最后,给出具体实例对所述方法加以验证。

| Abstract: | The bond graph method for dynamic simulation of linear system has been well established. But there are more work to be done for nonlinear system, because it is more complex both in formulating the state equations and in its solving. In this paper, the unified formulas of state-space equations of multiport nonlinear system are derived, mixed causality of the bond graph is taken into account, finite difference method and Broyden's quasi-Newton method are employed in solving this system of equations. Practical examples are used to verify the validity and generality of the method given in this paper. |
