“…In this section, we establish the mathematical modeling for the MAGC system. From (12), we can see that the mathematical model of the system has mismatched uncertainties and is with strict feedback form without considering the term (⋅). In order to address the problem of "explosion of complexity," we choose DSC technique to design the controller.…”

“…Therefore, many observer design methods have been proposed in existing literatures [5][6][7][8][9]. Compared with the traditional observer design method, an extended state observer (ESO) can be used to estimate the unknown uncertainties and disturbances, which can be found in [10][11][12]. As the MAGC model we construct in this paper has mismatched uncertainties, we will design a new ESO to estimate them and extend our method to a general high-order system.…”

The modeling and control problems are investigated for cold rolling mill system. Firstly, we establish a monitor automatic gauge control (MAGC) model for a practical cold rolling mill system. The new model is with mismatched uncertainties. Then, an extended state observer (ESO) is developed to estimate uncertainties. In the general high-order systems, the ESO is also used to estimate states. By dynamic surface control method, we design the controller to guarantee stabilization of the cold rolling mill system. Furthermore, we extend proposed method to general high-order systems, in which we analyze the difference from cold rolling mill system. Finally, simulation results for MAGC system are presented to demonstrate the effectiveness of the proposed control strategy.

Abstract. Firstly, this paper briefly describes the origin of the electromagnetic linear actuator which research status and development are summarised. Secondly, it describes the principle, the characteristics of the moving-coil linear motor and the Moving-magnet linear motor. Thirdly, it analyses and summarizes the key technologies of the electromagnetic linear actuator. One key problem is the matching between electromagnetic force and the load. The other is the influence mechanism of the thermal load on dynamic characteristics. This paper can provide some reference.

We present a light, actuated smart staff with 5DOF tip force sensing which can be used by a humanoid robot operating in challenging terrain. The staff has an extension mechanism that employs mechanical multiplexing to achieve a high extension ratio in a stiff and compact package. The tip force sensor uses two metal diaphragms to achieve decoupling of axial and radial forces and the ability to tune the maximum range of forces in each direction independently. With the force sensor, the robot can characterize the coefficient of friction and orientation of a surface with simple motion primitives. Two sets of experiments were conducted with the smart staff manipulated by a 7 DOF robot arm. Using the sensor, the robot was able to determine the orientations of sloped surfaces within two degrees in two orthogonal directions.
