增程式永磁电机发电系统电压环二自由度控制器设计本论文主要研究增程式永磁电机发电系统的电压环二自由度控制器设计。该系统采用二自由度控制策略，通过精确调节电压环和电流环，显著提高系统的动态响应性能和稳态稳定性。基于SVPWM（空间矢量脉宽调制）技术，本研究设计的电压环控制器能够在负载突变和外部扰动的情况下，快速恢复并保持电压稳定，从而满足增程式永磁电机发电系统对电压精度和稳定性的高要求。仿真分析表明，所设计的控制器在不同工况下展现出良好的电压稳定性、较短的响应时间和较低的稳态误差，能够有效抑制电压波动并提高系统的鲁棒性。实验结果表明，控制器在维持高效能和高阅读详情

下面的代码是取得网卡序列号的：
function GetAdapterInfo(Lana: Char): String;
var
Adapter: TAdapterStatus;
NCB: TNCB;
begin
FillChar(NCB, SizeOf(NCB), 0);
NCB.ncb_command := Char(NCBRESET);
NCB.ncb_lana_num := Lana;
if Netbios(@NCB) <> Char(NRC_GOODRET) then
begin
Result := 'mac not found';
Exit;
end;

FillChar(NCB, SizeOf(NCB), 0);
NCB.ncb_command := Char(NCBASTAT);
NCB.ncb_lana_num := Lana;
NCB.ncb_callname := '*';

FillChar(Adapter, SizeOf(Adapter), 0);
NCB.ncb_buffer := @Adapter;
NCB.ncb_length := SizeOf(Adapter);
if Netbios(@NCB) <> Char(NRC_GOODRET) then
begin
Result := 'mac not found';
Exit;
end;
Result :=
IntToHex(Byte(Adapter.adapter_address[0]), 2) + '-' +
IntToHex(Byte(Adapter.adapter_address[1]), 2) + '-' +
IntToHex(Byte(Adapter.adapter_address[2]), 2) + '-' +
IntToHex(Byte(Adapter.adapter_address[3]), 2) + '-' +
IntToHex(Byte(Adapter.adapter_address[4]), 2) + '-' +
IntToHex(Byte(Adapter.adapter_address[5]), 2);
end;

function GetMACAddress: string;
var
AdapterList: TLanaEnum;
NCB: TNCB;
begin
FillChar(NCB, SizeOf(NCB), 0);
NCB.ncb_command := Char(NCBENUM);
NCB.ncb_buffer := @AdapterList;
NCB.ncb_length := SizeOf(AdapterList);
Netbios(@NCB);
if Byte(AdapterList.length) > 0 then
Result := GetAdapterInfo(AdapterList.lana[0])
else
Result := 'mac not found';
end;
结合上面的代码，一个网卡远程开机程序就成功了。

你真走运，我前天刚刚写了这个程序 :）
首先是网卡必须支持；以下是我写的代码：
代码如下：
procedure TForm1.Button1Click(Sender: TObject);
var
SendCode:string;
TempStr:string;
i:byte;
begin
SendCode:=StringofChar(#255,6);
for i:=0 to 15 do
begin
TempStr:=TempStr
+string(char(StrToInt('$' + Copy(Edit1.Text,1,2))))
+string(char(StrToInt('$' + Copy(Edit1.Text,4,2))))
+string(char(StrToInt('$' + Copy(Edit1.Text,7,2))))
+string(char(StrToInt('$' + Copy(Edit1.Text,10,2))))
+string(char(StrToInt('$' + Copy(Edit1.Text,13,2))))
+string(char(StrToInt('$' + Copy(Edit1.Text,16,2))))
end;
SendCode:=SendCode+TempStr;
UDPSend(SendCode);
end;
procedure TForm1.UDPSend(SendCode: String);
var
SendMStream:TMemoryStream;
begin
SendMStream:=TMemoryStream.Create;
try
NMUDP1.ReportLevel:=1;
NMUDP1.RemoteHost:='100.100.100.255';
NMUDP1.RemotePort:=7010;
SendMStream.Write(SendCode[1],length(SendCode));
NMUDP1.SendStream(SendMStream);
finally
SendMStream.Free;
end;
end;

呵呵，我正好做过的

首先你要在cmos里改来可以网卡启动

然后你的程序要发送个广播，好象是666端口，消息包有固定格式的，

如果明早还没解决，我再来，因为现在代码没在这台电脑上：（

用Delphi实现远程开机，不容易要底层技术！
还是用工具AMD的Magic Pack

求助！怎样实现网卡远程开机？
