The algorithm combines the Levenberg-Marquardt algorithm with variable structure systems approach. The combination is performed by expressing the parameter update rule in continuous time and application of sliding control method to the gradient based training procedure. In this paper, a fuzzy inference mechanism that can be trained such that the adjustable parameter values are forced to settle down (parameter stabilization) while minimizing an appropriate cost function (cost optimization), is discussed. In the application example, control of a two degrees of freedom direct drive SCARA robotic manipulator is considered. As the controller, a standard fuzzy system architecture is used and the parameter tuning is performed by the proposed algorithm.","PeriodicalId":378710,"journal":{"name":"IECON'99.

A method for off-line determination of machine electrical parameters is presented. The measurement of the motor electrical variables at standstill time-domain test is used as an identification procedure base. Experimental results achieved with a 10 HP induction motor drive show good agreement between estimated and nominal electrical parameters. The proposed strategy is compared with other identification mechanisms, previously described in the literature, that have been improved with a proposed off-line current-dependent /spl sigma/L/sub s/ adaptation mechanism to obtain better accuracy. Results show similar behaviour using both identification schemes although the proposed scheme requires simpler tests.","PeriodicalId":378710,"journal":{"name":"IECON'99.

In order to show that the protocol is very sensible to loss of control frames (e.g. token frames), the authors evaluate three performance measures, using a simulation approach: the mean delay, the mean station outage time and the cumulated outage time, i.e. the fraction of time where a single station is not member of the ring due to loss or error of control frames. The results indicate that the PROFIBUS MAC protocol is not really a good choice for use over error prone links.","PeriodicalId":378710,"journal":{"name":"IECON'99.

Emphasis is placed on the DC drift and initial value problems due to the implementation of an integrator for motor flux estimation. Some existing algorithms together with a new improved integrator are presented and analyzed for showing their efficiency in terms of solving the problem associated with a pure integrator and achieving the combination objectives in both steady-state and dynamic operation.

Robotic manipulators are interfaced to the computer using simple microprocessor circuits. The engineering objective is to perform robust real time manual control over the Internet connection characterized by varying bandwidth and latency. A Web server is used to provide the client application to the operator. The client uses a custom TCP/IP protocol to connect to the server, which provides an interface to the specific robotic manipulators. Sensors and a video camera provide the feedback to the client. Since the decision was made that Java2 would be the only target implementation language both client and server are platform independent. The current system prototype \"Bradley WebBot\" utilizes an Intel based computer system with a Personal Web Server controlling remote controlled car models.
