沃尔什函数的理论近来在通讯工程中已有广泛的应用。它与Fourier级数的理论相比较,具有适合于数字系统转换的独特优点。沃尔什函数在自动控制理论中的应用也有少量的工作,目前仅限于对线性系统二次型指标的最优控制问题。本文的目的是应用沃尔什级数的方法,解决地空导弹最优制导规律中反馈增益矩阵的求取问题。可以指出,沃尔什级数 The theory of Walsh functions has recently been widely used in communication engineering. Compared with the Fourier series theory, it has the unique advantage of being suitable for digital system conversions. Walsh function in the automatic control theory also has a small amount of work, is currently limited to the linear system of quadratic index optimal control problems. The purpose of this paper is to apply the Walsh series method to solve the problem of obtaining the feedback gain matrix in the optimal guidance law of surface-to-air missiles. It can be pointed out that the Walsh series
