A novel adaptive sliding-mode observer is used for field oriented speed sensorless control. First the induced e.m.f. components are observed using the sliding-mode technique with an adaptive switching gain. Then a low-pass filter with an adaptive amplitude compensator, that works as derivative observer, is used to get rid of the chattering noise of estimated e.m.f. components and to calculate rotor speed and position. The current components in rotor reference frame are estimated from the active and reactive electromagnetic torques calculated in both the stationary reference frame and the estimated rotor one. The latter is also used as control reference frame. Inverter, filters and observer cause unavoidable and unpredictable time-delay in rotor position estimation, so that the control reference frame is delayed as to the actual rotor one. As a consequence, field orientation and maximum torque/current ratio do not occur when the desired field oriented current references are imposed in the control reference frame. An original field orientation PI controller is used to provide the appropriate current references in the control reference frame. Test results are presented to prove the approach effectiveness.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.

The stage is equipped with integrated built-in position sensor that uses the motor's electrode for position sensing. This stage is characterized by compact structure and low magnetic field emission. It can work within sufficiently small space in a vacuum chamber without disturbing surrounding electro-magnetic field. Therefore this motor stage could be highly compatible with many vacuum applications that utilize electron beam. In this paper, basic structure of the motor is described. The motor is sized 145 mm in length, 125 mm in width, and 40 mm in height. The stage is equipped with two thin plastic films, which contain three-phase electrodes aligned with an interval of 200 /spl mu/m. Those two films are attached to slider and stator, respectively, to generate electrostatic thrust force. Linear cross-roller guide supports the slider. The stroke is 40 mm. The estimated thrust force in 10/sup -3/ Pa is 1.2 N with an applied voltage of 1.6 kV/sub 0-p/. We have developed built-in position sensor for positioning servo control. Detail of built-in position sensor and results of positioning control are reported.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.

Existing product modeling methods offer quasi integration because appropriate integrated robot process model is not available. The authors propose a modeling of the robot system that has the capability of integrated description of product, robot and robot process. Advanced concepts as feature and associativity definitions together with task oriented robot process gained an extended application in the proposed model. This paper presents the new modeling for integrated application of part, assembly and robot process models at robot assembly of mechanical products. The main purpose of this integration is product model driven definition of robot assembly trajectories. The main contribution is an attempt to define shapes and part positions for robot assembly by using of form features instead of geometric elements. Form feature model objects carry intent of engineers for technical content of modeled environment. The paper introduces actual issues of robot assembly and outlines the concept of the authors for product model driven modeling of robot assembly. Information for assembly in feature based product model and robot process model features are explained. Following this, an extended feature concept for modeling of robot system is discussed. Finally, integrated model of robot assembly system and role of form features in it are concluded.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.

Such type of feedback implementation, wherein the control loops are closed through a real-time network, are called network controlled systems (NCS). When implementing a NCS, the underlying communication network must provide a timely communication service, which must be adequate to fulfill the control application requirements. Therefore, the assessment of the network responsiveness to the real-time requirements of the control application is a fundamental issue. Both PROFIBUS and CAN networks are usually considered suitable to support small-scale NCS, due to their real-time capabilities. However their temporal responsiveness is highly dependent on both the timing characteristics of the supported message streams, such as its periodicity and the related message lengths. In this paper, we compare the timing properties of both CAN and PROFIBUS control networks. Basically, we assess their capability to support network controlled systems, through the evaluation of the related worst-case message's response time. A small example of a NCS is then used to assess the capability of the CAN control network to fulfill control application requirements.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.
