Abstract
We consider a class of MIMO LTI models with uncertain resonant modes and time delays, which are common in control of instabilities arising in jet engines. With uncertain delays preventing the use of model reference adaptive control, we develop an adaptive MIMO pole placement scheme for the system. We use indirect adaptation, estimating a small number of physical parameters from a nonlinearly parametrized plant. To address the highly noisy environment in jet engines we introduce the deadzone in the adaptation law and present simulations that successfully stabilize the system in the presence of noise and severe actuator saturation.
