2. The result can be used in control problems whether the time interval is finite or infinite , the control set is bounded or unbounded , and also for systems with a weak differentiable function , i . e . , the function f is only strong continuously g - differentiable but not f - differentiable . so , th 6 . 2 . 7 is a uniform theory of optimal control , and it has wide - ranging applications
   可以看到，我們的結(jié)11摘要果可用于有限時域和無限時域、有界控制和無界控制、并且對系統(tǒng)中函數(shù)f的可微性要求也有較大的減弱? f對狀態(tài)變量x可以是僅有強(qiáng)連續(xù)的g一導(dǎo)數(shù)、不要求為f一可微。
3. Firstly , the identification of the double medium system is considered , the existence , the uniqueness and the boundness of the solution of the system of the partial differential equations are proved by using the monotone method , the mathematical model of the parameter identification problem is established , and under some mild assumptions , the optimality system about the identification is derived , thus the suitable gradient methods can be employed to solving the identification problem . secondly , the theories of optimal control of distributed parameter system are introduced to investigate the parameters identification problem involving the three - dimensional population system
