Metode Kontrol Skalar Dengan Penala Parameter PID Otomatis Menggunakan Algoritma PSO Sebagai Pengendali Kecepatan Motor Induksi Tiga Fasa Berbasis LabView

Abstract

This paper presents the PID parameter tuning automatically for three-phase induction motors with the V/F control method or scalar control. PID control is one type of simple control, its computation is light, easy to implement and known to be tough in dealing with disturbances. But PID has a weakness that is the difficulty of determining the optimal PID parameters, especially when applied to nonlinear systems such as speed control on a scalar control-based induction motor. Output tuning results automatically in the form of the best PID parameter data collection. This study was validated through simulations using the LabView application by testing dynamic speeds and dynamic loads. When testing using the automatic tuning algorithm PID parameters with parameters that have been optimized the Particle Swarm Optimization (PSO) algorithm, the dynamic speed performance characteristic results are better seen from the transient time in the form of average dead time and rise time of less than 1ms. The results of the Global Best Fitness from the PID automatic tuning simulation using the LabView-based PSO algorithm in the form of Kp, Ki, and Kd values can be used as input for setting the speed of the induction motor in real time.

Static and Dynamic Performance of Vector Control on Induction Motor with PID Controller: An Investigation on LabVIEW

“…In this research, the Ziegler Nichols method was used to obtain the parameter value of the PID. With the Ziegler Nichols method, the optimal PID parameter values are easily obtained through the open-loop system response [24]. Based on Figure 5, the limiter is used to limit the value of the PID parameter, so that it serves to improve the output of the PID control signal.…”
