This paper presents a classifier based on a net neural MLP (Multiple Layers Perceptron) using the algorithm of Levenberg-Marquardt to do the identification of the load of vehicles through the magnetic profile collected in equipment of control of traffic.
It is known that to monitor intrinsic life of transformers variables has been the object of concern in regard to avoid economic losses caused by faults in such equipment. It is possible through the system management, maximize the lifetime and improve grid reliability, which could also reduce maintenance costs. This paper brings a contribution to the development of these systems by proposing and testing...
The principle of vector control of AC machine enables the dynamic control of AC motors, and induction motors in particular to a level comparable to that of a DC machine. The vector control of currents and voltages results in control of spatial orientation of the electromagnetic fields in the machine and has led to term field orientation. Field oriented control schemes provide significant improvement...
In this work, a systematic method for self-tuning fuzzy PID control for SISO and MIMO systems is developed with practical application. The procedure consists in fuzzy self-tuning the parameters of a conventional PID controller located in the forward loop of the process. Fuzzy rules are used to determine the set of PID gains, based on the representation of human knowledge on how the margin of gain...
