Once the equivalent temperature was used, the loop would be guaranteed closed.
The controllers enforce stability and robust asymptotic reference-input tracking in the constrained uncertain closed-loop system and provide, at the same time, an explicit characterization of the region of guaranteed closed-loop stability.
A torque actuator is introduced in the upper riser package and a boundary control law is designed to generate the required signal for riser angle control and vibration reduction with guaranteed closed-loop stability.
The saturation indicators model the force limitations of the semi-active dampers in the LPV framework and thus allow for the synthesis of semi-active suspension controllers with guaranteed closed-loop stability and performance.
Effectiveness of the proposed algorithm is evaluated by simulations on a hard disk drive (HDD) benchmark problem, where the inter-sample position errors are approximately recovered and high-frequency disturbance is greatly attenuated with guaranteed closed-loop stability.
In this paper, a model predictive control scheme with guaranteed closed-loop asymptotic stability is proposed for a class of constrained nonlinear time-delay systems with discrete and distributed delays.
The first scheme provides performance guarantees by design, in the sense that it allows the user to select a desired suboptimal level of performance, where the degree of suboptimality provides a trade-off between the guaranteed closed-loop control performance on the one hand and the utilization of (communication/actuation) resources on the other hand.
Using a general state-space Lyapunov-based approach, the developed framework yields a direct nonlinear controller design method that integrates robustness, optimality, and explicit constraint-handling capabilities, and provides, at the same time, an explicit and intuitive characterization of the state-space regions of guaranteed closed-loop stability.
Oliver Pettit, from professional services company Deloitte, says key questions to network providers should include whether they can guarantee close to 100% network uptime.
Traders say that brokerage firms are hesitant to guarantee closing prices on Nasdaq in part because of the extreme moves sometimes seen in that market at the close.
