In this paper, the modeling and the control design problems for a Internal Bubble Cooling (IBC) system are considered. A dynamic model has been developed using a physical approach and validated with experimental measurement. The model has been used to design the closed-loop control architecture to regulated the bubble diameter. The controller has been tuned by simulation and its effectiveness has...
In this work the control system for a gravimetric feeder with vibrant duct for polymer extrusion process has been designed. The plant considered in this paper is a blending machine that mixes up to six components: each component is measured by a dedicated vibrant duct. All components are mixed directly in the chambers of the extruder screw. The mass delivered by each meter is measured by a load cell...
Self-balancing manual manipulators are devices that countervail the weight of a load that must be manually handled and moved by a human operator. An electric motor delivers the force needed to control the velocity of a spool with a metallic rope to which the load is hanged. This work concerns the tuning of the DC electric motor velocity controller. Specifically, Virtual Reference Feedback Tuning has...
This paper presents a full analysis and development of a system for vibrations reduction in a kitchen hood by using piezoelectric actuators. The control system is based on a feedback controller whose action depends on a single acceleration sensor collocated with the actuator. Two different resonant control laws have been designed: the first one operates without the information of the hood motor velocity;...
