The overall experimental system is depicted in Fig.1,
and it includes a FPGA (Cyclone EP1C20),a voltage
source IGBT inverter and a PMLSM.The PMLSM was
manufactured by the BALDOR electric company; and it
is a single-axis stage with a cog-free linear motor and a
stroke length with 600mm.The parameters of the motor
are:Rs = 27 Ω ,Ld = Lq = 23.3 mH,Kt = 79.9N/A.The
maximum speed and acceleration are 4m/s and 4 g but
depend on external load.The moving mass is 2.5Kg,the
maximum payload is 22.5Kg and the maximum thrust
force is 73N under continuous operating conditions.A
linear encoder with a resolution of 5µm is mounted on
the PMLSM as the position sensor,and the pole pitch is
30.5mm (about 6100 pulses).The inverter has three sets
of IGBT power transistors.The collector-emitter
voltage of the IGBT is rated 600V; the gate-emitter
voltage is rated ±20V,and the DC collector current is
rated 25A and in short time (1ms) is 50A.The photo-IC,
Toshiba TLP250,is used in the gate driving circuit of
IGBT.Input signals of the inverter are PWM signals
from FPGA device.For the implement,the PWM
switching frequency of inverter,dead-band and the
control sampling frequency of position loop are
designed to 12kHz,1µs,and 1kHz,respectively.

The overall experimental system is depicted in Fig.1,and it includes a FPGA (Cyclone EP1C20),a voltage source IGBT inverter and a PMLSM.整个实验系统描绘在图1中,它包括一个现场可编程门阵列（FPGA,Cyclone系列EP1C20）、一个电压源隔离栅双极型晶体管（IGBT）逆变器和一台永磁直线交流同步电机（PMLSM）.The PMLSM was manufactured by the BALDOR electric company; PMLSM是由BALDOR电气公司制造的；and it is a single-axis stage with a cog-free linear motor and a stroke length with 600mm.它是一种采用无铁芯线性电机的工作台（stage）和行程长度为600 mm的单座标（平移）工作台（stage）.The parameters of the motor are:Rs = 27 Ω ,Ld = Lq = 23.3 mH,Kt = 79.9N/A.电机的参数为：Rs = 27 Ω ,Ld = Lq = 23.3 mH,Kt = 79.9N/A.The maximum speed and acceleration are 4m/s and 4 g but depend on external load.最大速度和加速度为4 m/s和4 g,但取决于外部载荷.The moving mass is 2.5Kg,the maximum payload is 22.5Kg and the maximum thrust force is 73N under continuous operating conditions.在连续工作条件下,移动质量为2.5 kg,最大有效载荷为22.5 kg,最大推力为73 N.A linear encoder with a resolution of 5µm is mounted on the PMLSM as the position sensor,and the pole pitch is 30.5mm (about 6100 pulses).一台分辨率为5µm 的线性编码器被安装在PMLSM上作为位置传感器,磁极距为30.5 mm（大约6100个脉冲）.The inverter has three sets of IGBT power transistors.The collector-emitter voltage of the IGBT is rated 600V; 逆变器有三组IGBT功率晶体管.IGBT的集电极－发射极电压被额定为600 V； the gate-emitter voltage is rated ±20V,and the DC collector current is rated 25A and in short time (1ms) is 50A.栅极－发射极电压额定为±20 V,而直流集电极电流被额定为25 A,在短时间内（1 ms）为50 A.The photo-IC,Toshiba TLP250,is used in the gate driving circuit of IGBT.Input signals of the inverter are PWM signals from FPGA device.For the implement,the PWM switching frequency of inverter,dead-band and the control sampling frequency of position loop are designed to 12kHz,1µs,and 1kHz,respectively.东芝的TLP250 Photo-IC被用于IGBT的栅极驱动电路.逆变器的输入信号为来自于FRGA器件的脉宽调制（PWM）信号.对于实施来说,逆变器的PWM切换频率、位置环的盲带和控制取样频率被分别设计为12 kHz、1µs 和 1kHz.
