基于MATLAB_SIMULINK交流变频调速系统的仿真研究，对spwm交流变频调速进行仿真(spwm)

The book is organized for use as a text for an introductory course in stochastic processes at the senior level and as a?rst-year graduate-level course in Kalman ?ltering theory and application.It could also be used for self-instruction or for purposes of review by practicing engineers and scientists who are not intimately familiar with the subject.The organization of the material is illustrated by the following chapter-level dependency graph,which shows how the subject of each chapter depends upon material in other chapters.The arrows in the?gure indicate the recommended order of study.Boxes above another box and connected by arrows indicate that the material represented by the upper boxes is background material for the subject in the lower box.

Wireless Sensor Networks (WSNs) are comprised of thousands of sensor nodes, with restricted energy, that cooperate to accomplish a sensing task. Various routing Protocols are designed for transmission in WSNs. In this paper, we proposed a hybrid routing protocol: Zonal-Stable Election Protocol (Z-SEP) for heterogeneous WSNs. In this protocol, some nodes transmit data directly to base station while some use clustering technique to send data to base station as in SEP. We implemented Z-SEP and compared it with traditional Low Energy adaptive clustering hierarchy (LEACH) and SEP. Simulation results showed that Z-SEP enhanced the stability period and throughput than existing protocols like LEACH and SEP.
