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 传统的优化技术通常把各种控制要求结合而形成一个单独的性能指标，应用bellman的最优性原理或者庞特里雅金的极小值原理等使其最小化，从而得到问题的一次性最优解。
