本文对自校正调节器算法作了一些改进。首先提出了自校正调节器的一种近似算法。和自校正调节器的一般算法相比,该算法的特点是精度高、存储空间小和计算量少。本文还给出了抑制自校正调节器参数估计中矩阵 p(t)的方法。模拟计算表明,该方法有效地防止了 p(t)阵的激增(blow-up)。 This article made some improvements to the self-tuning regulator algorithm. First, an approximate algorithm of self-tuning regulator is proposed. Compared with the general algorithm of self-tuning regulator, the algorithm is characterized by high precision, small storage space and less computation. This paper also gives a method to suppress the matrix p (t) in the parameter estimation of self-tuning regulator. Simulation results show that this method effectively prevents the blow-up of the p (t) matrix.
