中文摘要 |
经典最小方差控制不能用于u(t)最高次幂u(t)p的系数多项式Bp(q-1)是不稳定的Hammerstein系统。基于经典二次型指标的控制加权一步最优控制亦难以推广到H系统。本文指出了文[3, 4]在研究此问题时的错误,提出采用对u(t)p加权的新性能指标,由此导出一种简单的直接自适应控制算法,证明了算法的局部收敛性。该算法可用于Bi(q-1), j=1, …, p稳定和非稳定的H系统的自适应控制。仿真结果证实了算法的优良性。 |
英文摘要 |
The classical minimum-variance control strategy can not be used for the control of the generalized Hammerstein model systems whose Bp(q-1), the coefficient polynomial of the highest power of u(t), is unstable. It is also difficult to extend the conventional control weighted on-step-ahead optimal control strategy to this class of systems. After pointing out the questionable point of [3] and [4] in studying the problem above, the paper proposes to use a new criterion which includes a weighting term on u(t)p and derives a simple direct adaptive suboptimal control algorithm. The algorithm can be used to control the generalized Hammerstein model systems irrespective of whether Bi(q-1), j=1, …, p are stable or not. The global stability and convergence of the proposed algorithm has been established and the simulation example is given to show the effectiveness of the algorithm. |
