Optimizing PID Controller Parameters in AVR Systems through GOA-Fuzzy Logic Integration

Problem Definition

The existing literature on tuning controller parameters for an AVR system has highlighted the use of the Grey Wolf Optimization Algorithm (GOA) to enhance the transient response. Although this approach has been considered efficient, a key limitation has been identified in the generation of constant PID controller values (Kp, Ki, Kd) at each iteration based on varying input signals. This lack of dynamic adjustment potentially hinders the system's efficiency and performance. Therefore, there is a pressing need to develop a method that allows for the dynamic variation of output values in response to changing input signals. By addressing this limitation, it is possible to create a more adaptive and responsive system that can better meet the dynamic requirements of an AVR system.

Objective

The objective is to develop a method that allows for the dynamic variation of output values in response to changing input signals for an AVR system. This method aims to improve the efficiency and performance of the system by integrating the Grey Wolf Optimization Algorithm (GOA) with a fuzzy logic-based system. By combining these two approaches, the goal is to create a more adaptive and responsive system that can better meet the dynamic requirements of an AVR system.

Proposed Work

In the above section, the various approaches proposed in literature for tuning of controller parameters are reviewed. As mentioned, one of the conventional works involves utilizing GOA to optimize PID controller parameters in an AVR system. However, the static output values generated by the GOA approach for varying input signals may not result in an efficient system. The proposed work aims to address this limitation by integrating GOA with a fuzzy logic-based system. The fuzzy logic approach is chosen for its ability to generate dynamic output values for varying input signals, thereby overcoming the inefficiencies of the previous GOA-based approach.

By combining the strengths of both methods, the proposed system can achieve a more efficient and flexible PID controller tuning process for the AVR system.

Application Area for Industry

This project can be utilized in various industrial sectors such as manufacturing, energy, automotive, and process control industries. The proposed solution of integrating fuzzy logic with the grasshopper optimization algorithm addresses the challenge of generating dynamic output values for PID controller parameters in response to varying input signals. In manufacturing industries, where precise control of machines is crucial, the dynamic tuning of controller parameters can lead to improved efficiency and productivity. In the energy sector, where stability and reliability are key factors, the flexibility of the system can enhance grid performance. Additionally, in automotive and process control industries, the ability to adapt to changing operating conditions can result in smoother operations and reduced downtime.

Overall, implementing these solutions can bring benefits such as increased efficiency, improved performance, and better system flexibility across diverse industrial domains.

Algorithms Used

The proposed work involves the integration of the Grasshopper Optimization Algorithm (GOA) with a fuzzy logic based system to tune the PID controller. The fuzzy logic approach is utilized to dynamically generate the proportional (Kp), integral (Ki), and derivative (Kd) values of the PID controller based on varying input values. By combining the capabilities of GOA and fuzzy logic, the PID controller can be fine-tuned more effectively. The system works by allowing both approaches to tune the PID controller independently and then fusing the best output values from each method. This results in a more efficient and flexible system for achieving the project's objectives.
