SMCSPO based force estimation for jetting rate control of 3D printer nozzle to build a house

Abstract

To use a 3D print for building, a method for jetting some materials should be different from the conventional method of an office type 3D print because the material usually used as mixed concrete with viscosity. This research discuss about SMCSPO based force estimation for a jetting rate control of the nozzle for simulation of the 3D building print. In this study, the concrete material is replaced with silicon in a pseudo 3D building print. When building an outer wall for simulation, it is important to jet a silicon with constant velocity and force. In order to jet the silicon with constant velocity and force, the reaction force occured from silicon should be estimated. This paper address that the jetting force is estimated by sliding perturbation observer and the actuator is controlled by sliding mode control algorithm.
