改进的自校正调节和全参数自适应控制算法

本文提出将受控对象差分方程参数总和趋一定理作为一个辅助方程与差分方程自身作赋权叠加的方案,以使调节器参数可以全部同时估计出来。由此引出了改进的自校正调节算法和全参数自适应控制算法。二算法的优点是运算量较小,对参数估计的初值假设要求不严格,参数估计和控制的收敛速度较快。

Modified Algorithms for Self-Tuning Regulator and All-Parameter Adaptive Controller

The idea that the tending-to-one theorem on parameter sum of the difference equation for the controlled plant can be used as an auxiliary equation superposed weightily upon the difference equation itself, is proposed in order to allow all STR parameters to be estimated simulta- nuously. Thus, modified algorithms for STR and all-parameter adaptive controller are developed. Both algorithms possess the advantages of less computational effort, looser assumption on initial values for parameter estimation and quicker convergence rale.
