【摘要】 尽管LQG控制具有很多优点,但由于计算量大,LQG 自校正控制仍未能得到成功应用。在本文,提出了一种新的 LQG 自校正控制器,它是基于最优控制理论和对象的输入输出模型设计的。该算法无需求解 Riccati 方程或进行谱因子分解,故计算量大为减小,易于实现。系统的闭环特性也在文中作了分析。更多还原

【Abstract】 Owing to large amount of computational labour,the LQG self-tuning controllershave not been used widely in spite of its many advantages.A new self-tuning con-troller based on optimal control and input-output plant model is presented,where thesolution of the Riccati equation and spectral factorization are not required.The algo-rithm is easy to implement and requires less computational labour than previous LQGself-tunners do.Analysis of some closed-loop properties is given in the paper.Simu-lation results demonstrate that this version of self-tuning controller possesses all theadvantages of an ordinary LQG control.更多还原
