| 摘 要： | 本文推导出一种新型加权无差自适应控制方法,它可以应用于开环不稳定系统及非最小相位系统,被控对象之中可以含有直接传输项.系统的稳态误差与加权参数的选择无关,而且理论与仿真均证明此算法的稳态误差为零.本文用此算法对火电厂中具有直接传输项和非最小相位的汽轮机主汽门调节系统进行控制仿真,并与其他算法进行了比较.其结果证明,此方法有较强的鲁捧性、可靠性与实用性.

| Abstract: | A new weighted adaptive control scheme is derived for the control of non-minimum phase and open-loop unstable systems,and there can be direct-transmission in the systems. The steady-state error oF the controlled system is independent of the choice of weighted parameters,and is zero by theoretical proof and simulation.The scheme is applied to the turbine throttling-valve control system of a 125 MW power plant,which has a direct
transmission and non-minimum phase.Compared with other adaptive control schemes,this new scheme is more selective,more reliable and more useful. |
