Agrarian Exploitations are introducing new Irrigation Systems with high technologies to prevent this problem, especially in the Mediterranean Region. An Irrigation System consists of several elements: aquifers, water pumps, a hydraulic network (pipes) and a great number of electro-values, which are far from the central post (in the order of km). to control the whole system is necessary to operate remotely every electro-value, which requires simultaneously control information (to open/close these electro-values) and power. The only way to operate with the lowest cost, is using a single wire for both, control and power. In this paper is shown a specific communication study for wide Irrigation Systems with Integrated Power Transmission, to carry out data communications over 2/spl times/1.5 mm section wires and distances no longer than 10 km, under very restrictive current consumption requirements, using OOK (On-Off Keying) modulation and a suitable filter design, both for transmission and reception.","PeriodicalId":119106,"journal":{"name":"1999 7th IEEE International Conference on Emerging Technologies and Factory Automation.

The algorithm combines the gradient descent technique with variable structure systems approach. The combination is performed by expressing the conventional weight update rule in continuous time and application of sliding mode control method to the gradient based training procedure. The proposed combination therefore exhibits a degree of robustness with respect to the unmodeled multivariable internal dynamics of gradient descent. With conventional training procedures, the excitation of this dynamics during a training cycle can lead to instability, which may be difficult to alleviate due to the multidimensionality of the solution space and the ambiguities on the free design parameters, such as learning rate or momentum coefficient. This paper demonstrates that a computationally intelligent system can be trained such that the adjustable parameter values are forced to settle down (parameter stabilization) while minimizing an appropriate cost function (cost optimization). The proposed approach is applied to the control of a robotic arm using feedforward neural networks.","PeriodicalId":119106,"journal":{"name":"1999 7th IEEE International Conference on Emerging Technologies and Factory Automation.

One of the main characteristics of the design is the flexibility. The system has to be adapted to the environment conditions and take actions depending on it. This influence is focused in the ability of the system to select the appropriate activity to be executed (depending on the available time) and to change its behaviour (depending on the environment information). The main goal of the paper is to characterise a model of tasks providing the required flexibility. The model has to be powerful enough to represent the functional and timing features of mobile robotic applications based on a behavioural architecture. Behavioural models have been largely used to represent advanced robotic systems which operate in uncertain dynamic environments combining information from several sensory sources and presenting different vehicle dynamics. The paper proposes the use of flexible tasks as a way to implement deliberative components in a behaviour architecture of a robot system and allows noteworthy run-time flexibility for introducing intelligent processes. Another important aspect considered in the paper is concerned with the relationship between the amount of time required by the tasks and the quality of the results obtained.","PeriodicalId":119106,"journal":{"name":"1999 7th IEEE International Conference on Emerging Technologies and Factory Automation.
