基于状态转移算法的非线性系统辨识与控制

Nonlinear system identification and control using state transition algorithm

Xiaojun Zhou, Chunhua Yang, Weihua Gui

摘要:

通过将非线性系统的辨识与控制问题转化为最优化问题,提出了一种新的最优化方法--状态转移算法(STA)。在所提出的STA中,最优化问题的解被认为是一种状态,并且解的更新等同于状态转换,这使得它易于理解并且便于实现。首先,STA被应用于识别与先前已知的结构的估计系统的最佳参数。在此基础上,利用STA优化设计了离线PID控制器。实验结果证明了该方法的有效性,并与STA和其他优化算法进行了比较,结果表明STA具有更强的搜索能力、更快的收敛速度和更稳定的性能,是一种很有前途的系统辨识和控制方法。

英文摘要:

By transforming identification and control for nonlinear system into optimization problems, a novel optimization method named state transition algorithm (STA) is introduced to solve the problems. In the proposed STA, a solution to a optimization problem is considered as a state, and the updating of a solution equates to a state transition, which makes it easy to understand and convenient to implement. First, the STA is applied to identify the optimal parameters of the estimated system with previously known structure. With the accurate estimated model, an off-line PID controller is then designed optimally by using the STA as well. Experimental results have demonstrated the validity of the methodology, and comparisons to STA with other optimization algorithms have testified that STA is a promising alternative method for system identification and control due to its stronger search ability, faster convergence rate and more stable performance.
