  This paper deals with event-triggered parameterized control (ETPC) of
nonlinear systems with external disturbances. In this control method, between
two successive events, each control input to the plant is a linear combination
of a set of linearly independent scalar functions. At each event, the
controller updates the coefficients of the parameterized control input so as to
minimize the error in approximating a continuous time control signal and
communicates the same to the actuator. We design an event-triggering rule (ETR)
that guarantees global uniform ultimate boundedness of trajectories of the
closed loop system. We also ensure the absence of Zeno behavior by showing the
existence of a uniform positive lower bound on the inter-event times (IETs). We
illustrate our results through numerical examples.
