Control of Stochastic Systems Subject to Sudden Change in Character

本研究将集中于一类非线性系统的控制器综合。 随机变化大扰动非线性系统 振幅 需要考虑的特殊问题是， 当设备具有有限数量的标称操作点时， 在这些点之间进行不频繁的转换。 的目标 工作是推广现有的分析程序，使更多的 现实约束可以包括在系统模型中， 创建计算上难以处理的设计方程。 特别 感兴趣的是包括传感器噪声和削弱 马尔可夫假说的主要外生干扰，通过取代它 一个更新的过程结构。 预计通过扩大 类允许的植物模型，将有可能改善 从而避免在后期阶段进行临时修改， 合成过程。

This research will focus on the synthesis of controllers for a class of nonlinear systems subject to randomly varying disturbances of large amplitude. The particular class of problems to be considered is that where the plant has a finite number of nominal operating points and makes infrequent transitions between these points. The goal of the work is to generalize existing analytical procedures so that more realistic constraints can be included in the system model without creating computationally intractable design equations. Of particular interest is the inclusion of sensor noise and the weakening of the Markov hypothesis on the primary exogenous disturbance by replacing it with a renewal process structure. It is expected that by extending the class of permissible plant models, it will be possible to improve the initial design thus avoiding ad hoc modifications in later stages of the synthesis process.
