Optimasi Kendali Suhu pada Sistem Nirkabel Penetasan Telur Berbasis PI dan PI Anti Windup

Abstract

The majority of commercially available chicken egg incubators use incandescent lamps as a heat source with temperature regulation using the on-off control and uncontrolled temperature fluctuations can occur. To overcome this, a control method based on Proportional Integral (PI), and anti-windup control was designed to produce optimal temperature control in the chicken egg incubator prototype and a transfer function model of the AC light dimmer module are used in the simulation for process analysis and comparison. The designed control algorithm is then implemented in a simulator in the form of a chicken egg incubator prototype composed of 2 nodes connected wirelessly. The sensor nodes will process input data using the BME280 temperature sensor and the actuator nodes will process the data using the PI control algorithm, and PI-anti windup control in determining the Pulse Width Modulation (PWM) output used by the AC light dimmer module to regulate light intensity of an incandescent lamp. The transfer function modelling uses the System Identification Toolbox (SIT) and the simulation design uses the Simulink Matrix Laboratory (MATLAB) software. Based on the results of the implementation and testing of the PI control and the PI-anti windup control, the system produces transient response characteristics that can determine a more optimal temperature control method. PI-anti windup control has transient response characteristics with a time constant value of 144,5 seconds, rise time of 226,5seconds, peak time of 322,5 seconds, settling time of 280 seconds, and delay time of 98 seconds, these results indicate that the PI-anti windup control algorithm is better than PI control.
