Frequency response based multivariable control design for motion systems [PDF]

, 2005
In this paper, we discuss the design of multivariablemotion controllers exploiting crosscouplings in the controller for open loop decoupling, disturbance rejection and feedforward decoupling.

Adaptive robust multivariable control of noninvertible memoryless systems with bounded disturbances: a generalization

Міжнародний науково-технічний журнал "Проблеми керування та інформатики", 2023
The discrete-time robust adaptive control for some classes of the uncertain multivariable memoryless (static) systems in the presence of unmeasurable bounded disturbances, whose bounds are assumed to be known is addressed.

Controlling Multivariable Systems with Significant Uncertainty

IFAC Proceedings Volumes, 1988
Abstract The problem of designing a robust controller for a multivariable system with significant uncertainty is considered. In particular, the class of uncertainty is represented by a set of finite demensional linear time-invariant models of the system.

Multivariable nonparametric learning: A robust iterative inversion‐based control approach

, 2021
Learning control enables significant performance improvement for systems by utilizing past data. Typical design methods aim to achieve fast convergence by using prior system knowledge in the form of a parametric model. To ensure that the learning process
