pidcode4.m

用于网络控制系统仿真

function [exectime, data] = pidcode4(seg, data)

switch seg,
    
 case 1,
  r = ttAnalogIn(data.rChan); % Read reference
  y = ttTryFetch('Samples');  % Read sample from mailbox
  data = pidcalc(data, r, y); % Calculate PID action
  exectime = 0.0018;
 case 2,
  ttAnalogOut(data.uChan, data.u); % Output control signal
  exectime = -1;

end
