— In this paper we propose a conditional integrator for solving the regulation problem of a class of nonlinear systems that probably possess unstable zero dynamics. The control scheme mainly takes advantage of the auxiliary controller proposed in  and a slow integrator. We present that the solution of the regulation problem can be cast as two auxiliary… (More)
Spleen tyrosine kinase (Syk), a member of Syk family of cytoplasmic non-receptor tyrosine kinases, is a key component of B cell receptor signaling and regulates multiple physiological functions of B lymphocytes in vertebrates. In the current study, a Syk homologue was identified in the lamprey Lampetra japonica (Lj-Syk). The cDNA fragment of Lj-Syk contains… (More)
An output feedback controller with adaptive conditional servocompensator is developed for robust output regulation of a class of nonlinear minimum-phase systems. It is shown that the controller achieves asymptotic regulation and can be tuned to recover the transient performance of a state feedback sliding-mode-controller.
