Received July 19, 2017 Revised Oct 20, 2017 Accepted Nov 7, 2017 Line tracking robots have been widely implemented in various applications. Among various control strategies, a proportional-integral-derivative (PID) algorithm has been widely proposed to optimize the performance of a line tracking robot. However, the motivation of using a PID controller, instead of a proportional (P) or a proport...

A NEW PI AND PID CONTROL DESIGN METHOD AND ITS APPLICATION TO ACTIVE QUEUE MANAGEMENT OF TCP FLOWS Deniz Üstebay M.S. in Electrical and Electronics Engineering Supervisor: Prof. Dr. Hitay Özbay June 2007 PID controllers are continuing to be used in many control applications due to their simple structures. Design of such controllers for unstable systems with time delays is an active research are...

This article proposes a Takagi-Sugeno Fuzzy (TSF) controller for vector control method applied in three-phase induction motor control. The conventional vector control method has two PI current controllers. With the aim to reduce the quantity of these controllers, it is proposed a unique fuzzy controller to substitute both PI controllers. The performance of the proposed TSF controller is analyze...

Absfracl-An industrial food processing plant consisting of nonlinear dynamics requires pressure and temperature controllers to he nonlinear. In this paper, nonlinesr controllers are designed using. fuzzy logic to augment the conventional pressure and temperature PI controllers for an industrial food processing plant. Simulation results are presented to show improvement in the plant response wit...

The development of high performance variable speed brushless dc motor drive is very important in all industrial applications. Generally, a high performance BLDC motor drive system must have good dynamic speed response, reference speed command tracking capability and load regulating response. Conventional controller such as PI, PID does not provide good dynamic response due to the problem of non...

Recently several robust control designs have been proposed to the load-frequency control (LFC) problem. However, the importance and difficulties in the selection of weighting functions of these approaches and the pole-zero cancellation phenomenon associated with it produces closed loop poles. Also the order of robust controllers is as high as the plant. This gives rise to complex structure of s...
