Control methods based on artificial intelligence techniques (learning algorithms, system identification and neural networks) can be applied to improve its performance. A neural control scheme is proposed, consisting basically of a neural network for learning the robot inverse dynamics and online generating the control signal. Also an online supervision based on optimisation techniques is designed and implemented for such neural control. Simulation results are provided to evaluate the alternative variations to the proposed central scheme.","PeriodicalId":119106,"journal":{"name":"1999 7th IEEE International Conference on Emerging Technologies and Factory Automation.

A periodic Producer/Consumer relationship is a paradigm used, in particular, in many real-time distributed applications like for instance distributed control applications. This study considers important mechanisms at the ATM switch level (buffering, concentration and scheduling aspects) and at the consumer architecture level (event triggered and time triggered). It is based on Stochastic Timed Petri Nets model and consist in evaluating the impact of the network load and the switch cell scheduling discipline on the performance of the producers/consumer application(cell loss probability, cell delay, average time between consumptions and vacant samplings and rejections).","PeriodicalId":119106,"journal":{"name":"1999 7th IEEE International Conference on Emerging Technologies and Factory Automation.

Provided extensions include earliest deadline first scheduling and real-time IPC service over ATM.
