Especially near the breakeven point a number of small companies, marketing costs were expected to be clear cut.

Second, the conventional linear optimal control can make system stabilize at neighborhood of balance point only. In this paper, we introduced a method of control by Artificial Neural Network. And also, identified variable on line. This method enhanced the adaptability of the control.

其次，由于常规的线性最优控制只能在平衡点附近稳定，这里利用人工神经网络在线识别不同运行状况下的各个参数值，离线训练网络，最后用训练成功的网络进行在线控制，实现了系统的大范围稳定。

Are also given by constructing Lyapunov function. Finally, by applying the energy methods, Sobolev embedding theorems and bootstrap arguments, the global existence of nonnegative classical solutions to equations with homogeneous Neumann boundary value condition is proved when the space dimension is at most 5. Under certain conditions for the coefficients of the reaction functions, the convergence of the solutions is established for the system with large diffusion coefficients by constructing Lyapunov function.

From the zero dynamics algorithm the norm form for general nolinear control systems is presented, which is extension of the affine nonlinear systems.

摘要研究了一般非线性系统的零动态算法，得到了应用广泛的正则标准形，只需对系统做较弱的正则性假设，即平衡点附近某些分布是非奇异的。

Then we discuss the stabilities of other fixed points, and prove the conditions appeared Hopf bifurcation by the Center manifold theorem and normal form.
