Abstract

Kepopuleran kontroler PID pada industri proses tidak lepas dengan kepraktisan yang dimiliki oleh kontroler jenis ini. Namun demikian, respons kontrol PID kurang memuaskan untuk dinamika sistem dengan disturbance, khususnya perubahan variable manipulasi flow input tangki sehingga memengaruhi variabel proses. Sehingga diperlukan penanganan gangguan tersebut melalui konsep kontrol cascade. Pada penelitian ini, digunakan metode kontrol PID-Firefly Algorithm (PID-FA) dalam mengendalikan sistem cascade flow dan level air pada PCT-100. Spesifikasi respons yang ingin dicapai, yakni time setlling 5% < 120 detik dan %overshoot < 5%. Penalaan PID oleh FA dilakukan serentak untuk PID inner dan outer loop sehingga mengurangi kerumitan penalaan cascade secara bertahap. Kemudian digunakan Integral Time Absolute Error (ITAE) sebagai fitness function atau fungsi objektif. Penelitian ini dilakukan secara simulasi dengan menggunakan software matlab dan simulink. Dalam pengujian hasil respons sistem, dibandingkan spesifikasi, seperti rise time, settling time, dan overshoot dari masing-masing kontroler. Melalui analisis komparatif respons sistem, kontrol cascade PID-FA mencapai spesifikasi respons yang diinginkan. Diketahui PID-FA lebih baik performanya daripada metode konvensional PID-ZN. Di lain sisi, kontrol cascade lebih baik daripada non-cascade dalam menangani adanya gangguan, baik oleh pembebanan maupun noise.

The popularity of PID controllers in process industries is inseparable from the versatility of this type of controller. However, the PID control response is not satisfactory for the dynamics of a system with disturbances, especially changes in the manipulated variable of the tank input flow, thereby affecting the process variable. Therefore, it is necessary to handle these disturbances through the concept of cascade control. In this study, the PID-Firefly Algorithm (PID-FA) control method was used to control the cascade flow and water level system on PCT-100. The desired response specifications are settling time 5% < 120 seconds and %overshoot < 5%. PID tuning by FA is carried out simultaneously for the PID inner and outer loop, thus reducing the complexity of cascade tuning gradually. Then, Integral Time Absolute Error (ITAE) was used as the fitness function or objective function. This research was conducted by simulation using Matlab and simulink software. In testing the system response results, specifications such as rise time, settling time, and overshoot of each controller were compared. Through comparative analysis of system response, PID-FA cascade control achieved the desired response specifications. It is known that PID-FA has better performance than the conventional PID-ZN method. On the other hand, cascade control is better than non-cascade in handling disturbances, both load disturbance and noise.
