Robust Control for Sampled-Data Systems via Digital PID Compensators.

PID and PDFF Compensators for Motion Control

Traditionally in servo systems, the PI(D) controller has been widely used, while other types such as the PDF controller has been applied in some applications. In this article, the PDFF controller which has feedforward term in addition to a conventional PDF(Pseudo-Derivative Feedback) controller is introduced. Tracking and regulation characteristics of the PDFF controller in motion control appli...

Robust Sampled-Data Control for Vehicle Active Suspension Systems

This brief investigates the problem of robust sampled-data control for active vehicle suspension systems. By using an input delay approach, the active vehicle suspension system with sampling measurements is transformed into a continuous-time system with a delay in the state. The transformed system contains non-differentiable time-varying state delay and polytopic parameter uncertainties. A Lyap...

Robust hybrid control for sampled-data delayed systems

Robust Sampled - Data Control of Switched Affine Systems

This technical note considers the stabilization problem for switched affine systems with a sampled-data switching law. The switching law is assumed to be a function of the system state at sampling instants and the sampling interval may be subject to variations or uncertainty. We provide a robust switching law design that takes into account the sampled-data implementation and uncertainties. The ...

robust stabilization for fuzzy network control systems with data drift

in this study, a robust controller is designed for fuzzy network control systems (ncss) using the static output feedback. delay and data packet dropout affect on the stability of network control systems, and therefore, the asymptotic stability condition is established considering delay and data packet dropout. delay is time-varying while the lower and upper bounds for delay is defined, and the ...
