We describe a technique to enhance both the weak-signal relative sensitivity and the dynamic range of a laser scanning optical microscope. The technique is based on maintaining a fixed detection power by fast feedback control of the illumination power, thereby transferring high measurement resolution to weak signals while virtually eliminating the possibility of image saturation. We analyze and...

In this paper, a low-computation adaptive self-triggered tracking control scheme is proposed for class of strict-feedback nonlinear systems with input saturation. By introducing two novel error transformation functions, the designed can overcome problem complexity explosion in absence any filters, such that developed more applicable. addition, to save communication resources networked systems, ...

This work investigates the anti-saturation attitude tracking control for tailless aircraft with guaranteed output constraints, in presence of uncertain inertia parameters, bounded external disturbance, and actuator faults/failures. A predefined-time adaptive backstepping scheme has been proposed, main features this lie (a) designing a filter to deal ‘explosion complexity’ singularity problem; (...

This study introduces an online reconfigurable road-adaptive semi-active suspension controller that reaches the performance objectives with satisfying dissipativity constraint. The concept of model is based on a nonlinear static Magnetorheological (MR) damper considering bi-viscous and hysteretic behaviors damper. input saturation problem has been solved by using proposed method in literature a...

Networks using wormhole switching have traditionally relied upon deadlock avoidance strategies for the design of deadlock-free routing algorithms. More recently, deadlock recovery strategies have begun to gain acceptance. In particular, progressive deadlock recovery techniques are very attractive because they allocate a few dedicated resources to quickly deliver deadlocked packets, instead of k...

It is discussed the problem of synthesis of the decentralized adaptive-periodic control system for two degrees of freedom robotic manipulator which have an input limitations. The solution of the problem is based on the use of hyperstability criterion, L-dissipativity conditions and dynamic filter-corrector. Keywords—adaptive control; combined regulator; serial dynamic corrector; hyperstability ...

Abstract The formation control problem for a group of first-order agents with model uncertainty and actuator saturation is investigated in this manuscript. An algorithm-and-observer-based controller developed to ensure the semi-global boundedness tracking error saturation. First, fully local-error-related cooperative weight tuning procedure proposed adaptive estimation each agent. effect on bot...

The redesign of output feedback controllers for linear systems based on adaptive saturation (stubborn) and dead-zone is investigated by showing that input-to-state stability holds in closed loop upon the satisfaction matrix inequalities. Such results are obtained using sector conditions involved Lyapunov analysis order to ensure stability. A simulation case study shows effectiveness proposed de...

We extend the adaptive regression spline model by incorporating saturation, the natural requirement that a function extend as a constant outside a certain range. We fit saturating splines to data using a convex optimization problem over a space of measures, which we solve using an efficient algorithm based on the conditional gradient method. Unlike many existing approaches, our algorithm solves...

Network-on-chip (NoC) is considered as a promising paradigm to overcome the communication bottleneck of future multicore systems. As a basic component in on-chip router, arbiter has a big impact on the performance of router. In this paper, we propose a novel dynamically adaptive arbiter which is based on the round robin mechanism. The proposed arbiter detects buffer status of input ports and ch...
