【摘要】 非整数阶系统辨识方法是建立非整数阶系统模型的一种重要工具.本文提出了一种非整数阶系统频域辨识的最小二乘递推算法.给出了算法的详细推导,并用已知系统验证了算法的有效性.结果表明该算法是整数阶系统辨识的最小二乘递推算法的推广.使用此算法,不但能辨识整数阶系统,还能辨识非整数阶系统.更多还原

【Abstract】 Frequency domain identification of non-integer order systems is a potent tool for modeling the non-integer systems.In this paper,a recursive least squares algorithm for frequency domain identification of non-integer order systems is presented.The algorithm is deduced in detail,and is validated with the known systems.The validation results show that the algorithm is the generalization of the the recursive least squares algorithm for integer order system identification,and not only the non-integer order systems but also the integer order systems can be identified with the presented algorithm.更多还原
