Control of Self-transfer-type Automatic Pouring Robot with Cylindrical Ladle
نویسندگان
چکیده
This paper is concerned with advanced control of self-transfer-type automatic pouring robot, with focus on the pouring control to cylindrical ladle and sloshing suppression (liquid vibration) control to the liquid in a ladle. In the pouring control, the flow rate model of cylindrical ladle is represented by LPV(Linear Parameter Varying) model, and FeedForward(FF) controller is then designed by using inverse systems of motor and flow rate model. In the sloshing suppression control, the natural frequency of sloshing of liquid in the ladle is varied by tilting ladle. Therefore, the natural frequency of sloshing is identified by using Short Time Fourier Transform, and the controllers are designed by Hybrid Shape Approach. The validity of proposed control system is demonstrated through experiments. Copyright c ©2005 IFAC

207/1 Nonlinear Modeling with Hydrodynamics and Flow Control Using Inverse Pouring Dynamics of Tilting-Ladle-Type Automatic Pouring Process
This paper is concerned with the pouring control of tilting-ladle-type automatic pouring systems in casting industries. A new approach to the modeling and control system of the pouring process is proposed. In the approach, the flow rate model is described by a nonlinear system with hydrodynamics. The flow rate control system is built by a feedfoward control using the inverse dynamics of the flo...
متن کاملA Novel Flow Rate Estimation Method Using Extended Kalman Filter and Sensor Dynamics Compensation with Automatic Casting Pouring Process
We describe here a method for estimating the pouring flow rate for tilting-ladle-type automatic pouring systems used in casting industries. To precisely pour molten metal into the mold, controlling the flow rate of liquid flowing out of the ladle is mandatory. However, it is difficult to directly measure the pouring flow rate by using a conventional flow meter, because the flow meter is damaged...

Humans manipulate fluids intuitively using approximations of the underlying physical laws. In this paper, we explore a general methodology that robots may use to develop and improve strategies for overcoming manipulation tasks associated with appropriately defined loss functions. We focus on the specific task of pouring a liquid from a container (pourer) to another container (receiver) while mi...
