Ltd 3Product Details -The unit incorporates all functions needed in a compressor control panel. Thus no additional modules are necessary resulting in lower panel cost.The early start function analyzes the air consumption trend and runs the compressor so that the pressure never falls below the low limit. The unit is directly supplied from the 230/400V utility network. It provides fail contact and sensor supplies internally. It needs 12V / 24V DC supply supply transformer in the panel.

Presentation Transcript Lead Controller Designplead zlead 20log(Kzlead/plead) Goal: select z and p so that max phase lead is at desired wgc and max phase lead = PM defficiency!Lead Design • From specs => PMd and wgcd • From plant, draw Bode plot • Find PMhave = 180 + angle(G(jwgcd) • DPM = PMd - PMhave + a few degrees • Choose a=plead/zlead so that fmax = DPM and it happens at wgcdLead Design Variation • There is ess and Mp requirement • From ess_d, compute K = ess/ess_d • Draw Bode plot of KG, find PM & wgc • From Mp specs, find PMd • fmax = DPM = PMd - PMhave + extraextraLead design example • Plant transfer function is given by: • n=[50]; d=[1/5 1 0]; • Desired design specifications are: • Step response overshoot n=[50]; d=[1/5 1 0]; figure(1); clf; margin(n,d); grid; hold on; ess2ramp= 1/200; Kvd=1/ess2ramp; Kva = n(end)/d(end-1); Kzp = Kvd/Kva; figure(2); margin(Kzp*n,d); grid; [GM,PM,wpc,wgc]=margin(Kzp*n,d); w_gcd=wgc; Mp = 20/100; zeta =sqrt((log(Mp))^2/(pi^2+(log(Mp))^2)); PMd = zeta * 100 + 10; phimax = (PMd-PM)*pi/180; alpha=(1+sin(phimax))/(1-sin(phimax)); z=w_gcd/sqrt(alpha); p=w_gcd*sqrt(alpha); ngc = conv(n, alpha*Kzp*[1 z]); dgc = conv(d, [1 p]); figure(3); margin(tf(ngc,dgc)); grid; [ncl,dcl]=feedback(ngc,dgc,1,1); figure(4); step(ncl,dcl); grid; figure(5); margin(ncl*1.414,dcl); grid;Problem • wgc moved to a new location • At a higher frequency • Phi_max was not at actual wgc • PM at actual wgc is too small • Solution: • Anticipate this upward wgc change • Place both z_lead and p_lead at a higher frequency than original wgcn=[50]; d=[1/5 1 0]; figure(1); clf; margin(n,d); grid; hold on; ess2ramp= 1/200; Kvd=1/ess2ramp; Kva = n(end)/d(end-1); Kzp = Kvd/Kva; figure(2); margin(Kzp*n,d); grid; [GM,PM,wpc,wgc]=margin(Kzp*n,d); w_gcd=wgc; Mp = 20/100; zeta =sqrt((log(Mp))^2/(pi^2+(log(Mp))^2)); PMd
