The traditional optimization technique usually combined the fundamental goal of the controller and performance criterion into a single performance index to be minimized by applying technique based on bellman ' s principle of optimality or pontryagin ' s minimum principle . this view of control is designed to obtain the best solution 傳統(tǒng)的優(yōu)化技術(shù)通常把各種控制要求結(jié)合而形成一個單獨的性能指標(biāo),應(yīng)用bellman的最優(yōu)性原理或者龐特里雅金的極小值原理等使其最小化,從而得到問題的一次性最優(yōu)解。
