   A Fuzzy Logic Calculation of the Duty Cycle for the Space-Vector Current Controlled PWM
By A. Dell'Aquila; M. Liserre; P. Zanchetta [View]
[Download]

Abstract: The paper presents an innovative current control technique of PWM converters that conciliates high dynamic response and low harmonic content. A novel space-vector control of the current is realised with a fuzzy logic estimation of the duty cycles for the vectors that reduce differently the error. The control has been tested on an inverter feeding an induction motor and the simulation results highlight a good current control with a very low value of harmonic distortion.

   Implementation of Adaptive Neural Network Real-Time Speed Controller for DC-Motor
By A. M. Zaki; H. M. Mashaly; A. Abdel-Sattar; S. Wahsh; S. I. Amer [View]
[Download]

Abstract: This paper presents an adaptive neural network speed controller for a seperately-excited dc motor. The control objective is to track the reference speed with the presence of dynamic changes. the weights and biases of the neural network are updated successfully on-line to regulate the control voltage. Two techniques are employed in this work, the first one utilized a fixed learning rate while the second one utilized an adaptive learning rate. The adaptive neurocontroller yields better transient response for both the speed and the current with adequately fast transient response and less oscillations than the fixed learning rate. Simulation and experimental results have been obtained for step change in the reference speed at constant load torque and also for step change in the load torque at constant reference speed.

   PMSM Robust Drive with H infinity Current Controller
By W. Sulkowski; P.-O. Nyman; D. Samuelsen [View]
[Download]

Abstract: This paper verifies the possibility of using a fixed robust H-infinity current regulator instead of a previously designed PI controller with decoupling in case of PMSM stator parameters varying over a wide range. The design of H-infinity current controller is discussed and practical results are shown to illustrate its advantages.

   Quasiperiodicity and Chaos in a Step Motor
By M. C. Péra; B. Robert; C. Goeldel [View]
[Download]

Abstract: Dynamic of a hybrid step motor is studied by tools of chaos theory, as Feigenbaum diagrams and Poincaré maps. A route to chaos by quasiperiodicity and a way out by period doubling are described and compared with the Curry and Yorke application and logistic map. Experimental results are reported which validate simulations.
