摘　　要：在现代控制系统中往往要对某一目标实现最优控制,从而达到某种预期效果,这使得现代控制系统的最优控制方法成为研究热点。最优控制问题往往就是一个极值问题,因此本文介绍了变分法的原理,指出了用变分法可以求得现代控制系统函数的极值,从而可以解决很多现代控制系统中的最优控制问题。通过实际验证,用变分法解决现代控制系统中的最优控制问题是一个行之有效的方法。People often want to achieve optimal control of a target to achieve a desired effect in Modem control systems, which makes the optimal control method of the modem control systems become a research hotspot .The optimal control problem is often an extreme problem . The paper introduces the principle of variational method , points out that the variational method can get the modem control system function extreme value, which can solve a lot of modem control system, the optimal control problem. It can be proved that using the variational method to solve the optimal control problem in the modem control system is an effective method.
