  1. Tips Penggunaan MATLABdalamPENGENDALIAN PROSES Ir. Abdul Wahid Surhim, MT.

  2. MencariAKAR POLINOMIAL • Matlabnya: • Fungsi standar untuk “akar” itu “roots” • roots([1.5 5 4.5 1])

  3. MembuatFUNGSI ALIH • Fungsi standar untuk “fungsi alih” itu “tf” G = tf(5, [1.5 5 4.5 1])

  4. Membuat GrafikFUNGSI STEP • Fungsi standar untuk “unit step” itu “step” G = tf(5, [1.5 5 4.5 1]) step(G)

  5. Membuat GrafikROOT LOCUS • Fungsi standar untuk “unit step” itu “step” G = tf(5, [1.5 5 4.5 1]) rlocus(G)

  6. Memasukkan Hargasetelah di-RUN • Memasukkan harga atau nilai setelah program di-run dilakukan untuk simulasi • Fungsi standarnya “input”: Kc=input('Masukkan harga Kc: '); Ti=input('Masukkan harga Ti: '); Td=input('Masukkan harga Td: ');

  7. Simulasi Sistem Pengendalian Proses Heat Exchanger: Sensor: Control Valve: Kontroler PID:

  8. Kode MATLAB Kc=input('Masukkan harga Kc: '); Ti=input('Masukkan harga Ti: '); Td=input('Masukkan harga Td: '); tn=input('Waktu akhir: '); h=input('dt: '); Gc=Kc*tf([Ti*Td Ti 1],[Ti 0]); Gv=tf(0.016,[3 1]); Gp=tf(50,[30 1]); Gs=tf(1,[10 1]); Kp=0.8; n=Gc*Gv*Gp; d=1+Gc*Gv*Gp*Gs; % SERVO (Setpoint) G=n/d; t=0:h:tn; step(G,t) [y,t]=step(G,t); n=length(t); IAE=0; for j=2:n IAE(j)=IAE(j-1)+h*abs(1-y(j-1)); end pause plot(t,IAE) IAE=IAE(n)
