Concerning the problem that the traditional method is not valid to demodulate the MSK signal, this article is the first time to use Duffing oscillator and Stochastic Resonance to demodulate the MSK signal, a new demodulation method was proposed in this article. First, we put the MSK's frequency compressed into a low range; then, we put the MSK signal into the Stochastic Resonance system to increase...
As the prevalence of broadband coherent sources, a novel algorithm for the direction of arrival (DOA) estimation of coherent signals based on DPT and virtual array is introduced. And one of the algorithms is to be done a comparison, analysis and improvement. It can settle the problem of not finding coherent signals in routine algorithm. This approach can estimate accurately and do not decrease effective...
This paper presents a novel Hybrid Space Vector Control scheme for the vehicle IPMSM, possessing the advantages of both vector control and cascaded multilevel PWM. This scheme can provide the high-voltage vehicle IPMSM with the high-quality, approximate sinusoidal voltage source, meanwhile, it can realize various advanced closed-loop control methods, which is very fit for the vehicle inverters. Simulation...
A new tracking scheme with the three sine parts controlled independently from each other is presented in this paper, by using this scheme, the switching signals of the three phases can be acquired at the same time, it can track any given magnetic flux to control the flux. By comparing the tracking and contrast, the switching state of each phase can be acquired, and combine the switching state of phase...
About pedestrian micro-simulation, no matter in continuous space or discrete space, an important problem is collision avoidance. The paper focus on three kinds of collisions and their solutions in discrete space, meanwhile, describes the solution steps and processes in continuous space.
In this paper, a full order state observer fit for the speed and rotor position is proposed. It can obtain the good tracking performance in the full speed region. In the low speed region, it adopts the high frequency injection method, thus obtains the corresponding high frequency current response which includes the rotor position information, after the band-pass filter and low-pass filter, the signal...
