针对受输入非线性和外部干扰影响的指数稳定、线性、离散、无限维控制系统,提出了一种具有抗卷积分量的低增益积分控制器。我们得到了扰动-状态稳定性的结果,特别是保证了在没有扰动的情况下跟踪误差收敛于零。然后将离散时间结果用于具有非线性输入的稳定的良定线性无限维系统的采样数据低增益积分控制。将采样数据控制方法应用于两个实例(包括正方形上热方程的采样数据控制),并对其进行了详细的讨论。
A low-gain integral controller with anti-windup component is presented for exponentially stable, linear, discrete-time, infinite-dimensional control systems subject to input nonlinearities and external disturbances. We derive a disturbance-to-state stability result which, in particular, guarantees that the tracking error converges to zero in the absence of disturbances. The discrete-time result is then used in the context of sampled-data low-gain integral control of stable well-posed linear infinite-dimensional systems with input nonlinearities. The sampled-date control scheme is applied to two examples (including sampled-data control of a heat equation on a square) which are discussed in some detail.
