This paper aims to investigate the performance of a bidirectional DC-DC converter utilizing an ANFIS-PID controller in closed-loop mode. This is because operating a bidirectional DC-DC converter in open-loop mode can result in several problems, including poor regulation, limited flexibility, and limited performance, especially in transient response and efficiency. Additionally, there is a risk of […]
In order to analyze the mathematical modeling and PID controller performance of a quadrotor, this paper firstly, describes the quadrotor flight dynamics according to “Newton-Euler laws”, then equations of motion linearized and transfer functions for 6 degree of freedom obtained in state space domain. Classic PID controller based on “Ziegler-Nichols method” is designed and implemented […]
Engines with variable poppet valve timing systems are among numerous efforts that aim to reduce engine emissions and/or increase efficiency. In the present paper we have investigated the stability of a magnetic valve system in MATLAB. First we designed the magnet and interactive forces inside the electromagnetic valve system, then we produced a mechanical model […]
As a real time process, in tuning the coefficients of PID controllers in AVRs, accuracy vs. speed is an important issue. Considering complexity of the problem and real systems requirements, various methods, including exact methods and approximation algorithms, have been implemented for this purpose. Since the conventional methods based on meta-heuristic algorithms solving this problem, […]
Load frequency control is an important factor of supplying quality electricity in an interconnected power system. As a result, an optimally tuned Proportional-Integral-Derivative (PID) controller is proposed in this work to eliminate frequency errors caused by unexpected load changes while maintaining tie-line power exchange. The PID controller is tuned using several optimization techniques such as […]
Providing reliable and sufficient power to the client is essential. Power quality is determined by the consistency of frequency and tie-line power between control regions. Thus, the importance of Load Frequency Control in an electrical network cannot be overstated. In this work, a PID controller using the Grey Wolf Optimization algorithm is employed to help […]
