Modified S-Plane Control of AUV Based on Motion Compensation

2009 International Workshop on Intelligent Systems and Applications, 2009
S-plane control is proved to be a feasible method with disadvantages at high speed in application to AUV motion control. To compensate the motion couple effect at high speed, a modified S-plane controller is proposed by analyzing AUV's dynamics and taking static force and coupling effects between longitude velocity and other dimensions into account ...

S Plane Control of underwater vehicle and its hybrid training algorithm

2009 Chinese Control and Decision Conference, 2009
For the particular control object of automatic underwater vehicles (AUV), an S Plane Control based on the analysis of fuzzy control and combined with the form of PID control is introduced which is a simple and effective method, but parameters must be manually set for its controller.

Stability Analysis on S Plane Control of Underwater Vehicles

Applied Mechanics and Materials, 2013
This paper addresses the stability analysis on S Plane Control in terms of both position and velocity control. Employing Lyapunov stability theory and T-passivity theory, this paper proves the stability of the position controller based on S Plane Control, and on this ground, the stability analysis of the velocity controller based on S Plane Control is ...

S-Plane-Based Trajectory Tracking Control of Underactuated Ship

2021 4th International Conference on Intelligent Autonomous Systems (ICoIAS), 2021
It is well known that traditional trajectory tracking model-based control methods of underactuated ship are not able to adapt to complex and dynamic ocean environment. In this paper, taking into consideration of dynamic parameter uncertainty of the underlying underactuated ship model and unknown time-varying environmental disturbances, an S-plane-based

Improved PSO-based S Plane Controller for motion control of underwater vehicle

2008 Chinese Control and Decision Conference, 2008
Based on the analysis of fuzzy control, combined with the form of PID control, the S plane control has been applied. For the default that particle swarm optimization (PSO) presents the phenomenon of precocity and getting in local minima, the basic PSO algorithm is improved.

Fuzzy S plane controller for motion control of underwater vehicles

2011 6th IEEE Conference on Industrial Electronics and Applications, 2011
Autonomous Underwater Vehicle (AUV) has a strong-coupling nonlinear motion system. Thus, nonlinearity must be considered in the design of AUV' control system. And the control method which is independent of model must be taken into account, too. Fuzzy S plane controller was adopted to solve the motion control problem under various velocities in the ...

A s-plane analytic technique for lead-lag controller design

Proceedings of 1995 American Control Conference - ACC'95, 2005
In this paper an analytic design technique for a lead-lag controller to satisfy specifications for transient and steady state response of a plant is proposed. Based on the s-plane, three closed loop roots after lead-lag compensation are forced to line up on one vertical line, then the prefiltering technique is used to cancel out undesired effects of ...

Chi: A Scalable and Programmable Control Plane for Distributed Stream Processing Systems

Proceedings of the VLDB Endowment, 2018
Stream-processing workloads and modern shared cluster environments exhibit high variability and unpredictability. Combined with the large parameter space and the diverse set of user SLOs, this makes modern streaming systems very challenging to statically

Dynamic Control Plane for SDN at Scale

IEEE Journal on Selected Areas in Communications, 2018
As SDN migrates to wide area networks and 5G core networks, a scalable, highly reliable, low latency distributed control plane becomes a key factor that differentiates operator solutions for network control and management.
