採用逐次逼近演算法給出了系統前饋反饋最優控制律的設計方法,利用擾動觀測器解決了最優控制律的物理可實現問題。Such methods are generally decreasing method, such as, feasible direction methods, constrained variable metric methods, etc. another class is sub - problems method, which approximates the optimal solution by solving a series of simple sub - problems, such as penalty function methods, trust region methods, and successive quadratic programming sub - problems, etc. the same property of two classes of methods is that they determine whether the next iterative point is " good " or " bad " by comparing the objective function value or merit function value at the current point and next iterative point
另一類叫做子問題演算法,這種演算法是通過一系列簡單子問題的解來逼近原問題的最優解,如罰函數法、信賴域演算法、逐步二次規劃演算法等。這兩類演算法的一個共同特點是,通過比較當前點和下一個迭代點的目標函數值或評價函數值來確定迭代點的「優」或「劣」 ,若迭代點比當前點「優」則該迭代點可以被接受,否則須繼續搜索或調整子問題。A set of calculation softwares was programmed by simulated annealing algorithm. these softwares can find the best solution without being given initial values but region of convergence, and have a lot of advantages such as fast convergence, good stability and high accuracy
根據模擬退火演算法編制的一系列計算軟體能在大面積內快速搜索,無須給定初始值,只要給定收斂區間,就能對可疑的點進行逐次逼近,直至搜索到一組最佳的薄膜參數值。
