A method for synthesizing dynamic output feedback controllers for continuous time systems presenting actuators constrained in both amplitude and rate is proposed here. The considered controller structure is composed of a saturating integrator block connected to a linear compensator output, delivering a signal to the actuator input inside all its bounds. Considering that the plant is submitted to L 2 bounded disturbances, linear matrix inequality conditions are proposed in order to ensure both external and internal stability of the closed loop system.
