Feedfoward control is widely used to compensate measurable external disturbances. This paper studies feedforward control using an event-triggered sensor. Stability conditions when the feedback control is subject to actuator saturation are derived. We also obtain stability conditions of eventtriggered feedforward control with anti-windup compensation. A numerical example shows that event-triggered feedforward control significantly reduces communication between the sensor and the controller without performance degradation compared with continuous-time feedforward control.
