Adaptive learning-based recoil control for deepwater drilling riser systems
Ocean Engineering, 2023This paper deals with the adaptive learning based recoil suppression control problem of deepwater drilling riser systems subject to parametric perturbations, platform heave motion, and friction resistance force of drilling fluid discharge. First, a stochastic configuration network based approximator is presented to predict the friction resistance force

Optimal Control of Gun Recoil Using Magnetorheological Dampers
Volume 2: Mechanics and Behavior of Active Materials; Integrated System Design and Implementation; Bio-Inspired Materials and Systems; Energy Harvesting, 2012Optimal control of a gun recoil absorber is investigated for minimizing recoil loads and maximizing rate of fire. A multi-objective optimization problem was formulated by considering the mechanical model of the recoil absorber employing a spring and a magnetorheological (MR) damper.

Detection and Control of Bubble Entrapment During the Recoil Phase of Droplet Impact
2020 IEEE 33rd International Conference on Micro Electro Mechanical Systems (MEMS), 2020In this paper, we report a method to detect the formation of bubble during the recoil phase of droplet impact on a (super-)hydrophobic surface using a MEMS-based acoustic sensor. We show that by this method, not only the occurrence of bubble entrapment can be detected but also the size of the bubble can be measured from the frequency of the oscillation

Notice of Retraction: Research for fuzzy control system of recoil tension
2011 Second International Conference on Mechanic Automation and Control Engineering, 2011According to researches recoil tension about automatic control system, through the current regulator to control the system. Not only keep the dynamic and static better, but also make interference immunity better. It avoids the shape tower in the process of recoiling, so it can accomplish rather better control result, satisfy the request of customers.
