A 65-year-old man presented to ambulatory care with a 10-month history of muscle weakness, weight loss, dysphagia and fatigue. Prior to presentation he had been managed in general practice for hypothyroidism with a low T4 level and normal thyroid sti

This paper considers non-linear regulation and angular momenta management of a Space Station in the presence of a disturbance torque. The sinusoidal aerodynamic disturbance torque is treated as the output of an exosystem. An output zeroing submanifol

Modern microprocessor capabilities permit the control designer to consider using relatively complicated nonlinear control algorithms, which would have been considered impractical in the past. This paper presents the results of a study of the variable

The problem of joint stabilization and tracking of a spinning satellite system in addition to its regulation are considered. The rational fractional approach is used to obtain coprime equations in a multivariate setting for both coupled and decoupled
