MINIMUM-LEARNING-PARAMETER-BASED FAULT-TOLERANT CONTROL FOR SPACECRAFT RENDEZVOUS WITH UNKNOWN INERTIAL PARAMETERS

Minimum-Learning-Parameter-Based Fault-Tolerant Control for Spacecraft Rendezvous With Unknown Inertial Parameters

In this paper, robust control strategies are explored to solve the problem of rendezvous maneuver for rigid spacecraft exposed to the external disturbance, actuator faults and unknown inertial parameters.To pursue the control objective, two adaptive controllers are constructed via the sliding mode control (SMC) technology.Firstly, a basic control s

Parameter Estimation for Robotic Manipulator Systems

In this paper, a novel methodology for estimating the parameters of robotic manipulator systems is proposed.It can be seen that, for the purpose of parameter estimation, the input torque to each joint mpu63zm/a motor is designed as a linear combination of sinusoids.After the transient responses of joint angles exponentially converge to zero, the st

Methotrexate and mucositis: A merry-go-round for oncologists

High-dose methotrexate is the backbone of various regimens for treating lymphoid malignancies.Mucositis is a well-known, dose-related side effect of methotrexate.Prophylactic measures such as folinic acid rescue are useful but steely dan gaucho t-shirt do not prevent mucositis in all the cases.Once severe mucositis whip carbon magnum (WHO Grade IV)

Interpretation of indoor air surveillance for respiratory infections: a prospective longitudinal observational study in a childcare settingResearch in context

Summary: Background: Sampling the air in indoor congregate settings, where respiratory pathogens are ubiquitous, may constitute a valuable yet underutilised data source for community-wide surveillance of respiratory infections.However, there is a lack of research comparing air sampling and individual sampling of dodge charger carbon fiber spoiler a
