摘要
给出一种新型的非线性放大器,称它为均方根放大器(SQF),用它可以大幅度提高优化控制系统的品质指标。作为范例,用它来改善已获广泛应用的ITAE最优控制系统。实验结果表明,该放大器显著提高了ITAE最优控制系统的品质指标,并给出了再优化后系统标准型传递函数,供工程人员选用;同时,也可推广用于提高任何优化控制系统的品质指标,具有很好的应用前景。
A new nonlinear amplifier which called square.root amplifier was proposed for greatly improving thequality indicators of optimal control systems. As an example,SQF was applied to improve ITAE optimal controlsystems[1-11]which are widely used in the industry. Experiment results show that the SQF significantly improves thequality indexes of ITAE optimal control system,and also the transfer functions of re.optimization control systems aregiven for engineers to use. Finally,the SQF can be applied to any optimal control system to improve the qualityindicators and it will have good application prospects.
