论文摘要
通常需要在相对较短的将来的时间内预测系统的状态以进行控制。但是，当系统受到外部干扰的影响时，其未来状态取决于即将发生的干扰。在大多数情况下，这是未知和无法衡量的。在这种情况下，对未来系统国家的预测并不直接，实际上，对这个问题提供了稀缺的贡献。本文处理以下问题：鉴于受LTI系统受到连续不同的未知干扰影响的LTI系统，如何通过高阶观察者在足够小的时间疗法中预测其未来状态。观察者设计方法为了减少预测错误。还建立了与其他解决方案的比较。
Predicting the state of a system in a relatively near future time instant is often needed for control purposes. However, when the system is affected by external disturbances, its future state is dependent on the forthcoming disturbance; which is, in most of the cases, unknown and impossible to measure. In this scenario, making predictions of the future system-state is not straightforward and, indeed, there are scarce contributions provided to this issue. This paper treats the following problem: given a LTI system affected by continuously differentiable unknown disturbances, how its future state can be predicted in a sufficiently small time-horizon by high-order observers. Observer design methodologies in order to reduce the prediction errors are given. Comparisons with other solutions are also established.
