| Summary: | System Identification is a method for determining the dynamic model of a system from input and output measurements of the system. Knowing a model system is needed to design and implement control systems with optimal performance. System identification is an experimental approach for determining the dynamic model of a system.
Based on the results of closed-loop identification with algorithm closed-loop output error (CLOE) condenser system plant model is obtained and the control valve is of second order system. Analysis of responses transient and steady state of model in a closed loop system with exciting controller in the plant showed a fast oscillating with a settling time 4.28 seconds, peak time 3.58 seconds, rise time 0.756 seconds and no error steady state.
Re-tuning control system gives the best results in response system using proportional-integral controller (PI) with the principle of ISE. The aim of re-tuning is to find the controllers constant that provides optimum performance and gives safety of the system especially in the actuator and the final element. Simulation results using MATLAB software shows the settling time of 24.7 seconds, peak time 3.57 seconds, rise time of 1.03 seconds and no steady state error occured. Controller constants the results of the re-tuning proportional band (K) is 260.34%, integral time (Ti) is 0.36 seconds and the time derivative (Td) 0 seconds. |
