SUMMARY
Systems in industry often occur in performance or desired performance. One of them isothermal CSTR system where the system has not been able to work according to the desired set point 1 g.mol / litter, to achieve the set point then used the controller Sliding Mode Control in Hybrid with Fuzzy Logic Controller in identification with FOPDT method to lower the value steady state error. hybrid sliding mode control and fuzzy logic controller has reached the desired set point value of 1 g.mol / litter with settling time 0.7098 sec while sliding mode controller has steady state error 0.0004 g.mol / litter with time steady / settling time 0.7275 seconds
