  1. Pengendalian Proses Priyatmadi Jurusan teknik Elektro FT UGM Process Control Priyatmadi 2005 1

  2. CONTROL ACTION • ON-OFF • PROPORTIONAL (P) • PROPORTIONAL + INTEGRAL (PI) • PROPORTIONAL + DIFFERENTIAL (PD) • PID • ADAPTIVE • FUZZY • Auctioneering • ETC Process Control Priyatmadi 2005 2

  3. m M1 e M2 ON-OFF CONTROL ACTION Set point r(t) c(t) e(t) + m(t) Plant Controller • m(t) = M1 if e(t)>0 • m(t) = M2 if e(t)<0 - c(t) Sensor Process Control Priyatmadi 2005 3

  4. M1 e M2 ON-OFF CONTROL ACTION WITH GAP Set point r(t) c(t) e(t) + m(t) Plant Controller • m(t) = M1 if e(t)>e1 • m(t) = M2 if e(t)<e2 - c(t) Sensor m e2 e1 Process Control Priyatmadi 2005 4

  5. qi(t) Level sensor h(t) qo(t) example Process Control Priyatmadi 2005 5

  6. example Process Control Priyatmadi 2005 6

  7. m(t) e(t) t Proportional Control Action Set point r(t) c(t) e(t) m(t) + Plant Controller • m(t)=Kpe(t) - c(t) Sensor Process Control Priyatmadi 2005 7

  8. Integral Control Action Set point r(t) c(t) e(t) m(t) + Plant Controller • m(t)=Ki∫e(t)dt - c(t) Sensor m(t) e(t) t Process Control Priyatmadi 2005 8

  9. Derivative Control Action Set point r(t) c(t) e(t) m(t) + Plant Controller • m(t)=Kd(de(t)/dt) - c(t) Sensor m(t) e(t) t Process Control Priyatmadi 2005 9

  10. Advance control • Auctioneering • Ratio • Adaptive • Fuzzy • etc Process Control Priyatmadi 2005 10
