PMSM-control
永磁同步电动机调速系统由pmsm月吸逆变器、永磁同步电动机和机械负载三部分组成,每个部分都具有非线性特性和参数的不确定性。因为PWM逆变器死区的存在,在低速以及调制频率很高时,死区特性将会导致逆变器输出电压包含很大的谐波分量,使得电机转矩发生很大的
脉动,甚至导致系统的不稳定。有些学者采用变结构控制降低死区的影响,由于变结构控制本身具有抖振现象,这使得所设计的控制器在到达滑模平面之前很容易激起系统的未建模动态,导致系统无法克服逆变器死区的影响。

Probability.Statistics.and.Random.Processes.For
This book provides a carefully motivated, accessible, and interesting introduction to
probability, statistics, and random processes for electrical and computer engineers.The
complexity of the systems encountered in engineering practice calls for an understanding
of probability concepts and a facility in the use of probability tools.The goal of the
introductory course should therefore be to teach both the basic theoretical concepts
and techniques for solving problems that arise in practice. The third edition of this
book achieves this goal by retaining the proven features of previous editions:
