Mandarin speech has four different tones and the coding mechanism underlying tone identification still remain unclear. Here in the inferior colliculus (IC) of anesthetized guinea pigs, we recorded single neuron activities to one word with four tones using tungsten electrode. Peri-stimulus time histograms (PSTHs) and inter-spike-interval (ISI) were used to evaluate the neural response. The results...
In this paper, the optimization problem for switched reluctance motor (SRM) is discussed and the convex optimization method is applied to calculate SRM control parameters instead of parameter sweeping. An optimal approach to calculate the maximum torque at each speed is presented. Also, a method to optimize control parameters is presented to minimize the copper loss for the given speed and torque...
This paper presents a design of space-vector PWM (SVPWM) integrated circuit. The proposed strategy is implemented and verified on a single Altera's Cyclonetrade series of FPGA (EPICF400C7). Experimental results show that this controller can present an excellent drive performance and its switching frequency, as well as its dead time, is adjustable. The design can be used in vector control of AC servo...
