In this paper, a new improved Differential Search Algorithm optimization approach is proposed and successfully applied to the design and tuning of a PID-type Fuzzy Logic Controller. The scaling factors tuning problem of the Fuzzy Logic Controller structure is formulated and systematically resolved, using the improved constrained Differential Search Algorithm-based method. A comparison, with the...

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...

This paper presents a recent development of PID controllers. The proposed controller design aims to overcome the drawbacks of classical PID controller, such as: integrator windup due to the saturation in the actuator and the slow response to reject disturbances. Classical approaches to treat the windup problem in PID controller design are discussed and analyzed such as conditional integration m...

The rapid growth of the Internet and increased demand to use the Internet for voice and video applications necessitate the design and utilization of new Internet architectures with effective congestion control algorithms. As a result the Diff-Serv architectures were proposed to deliver QoS in TCP/IP networks. Network congestion control remains a critical and high priority issue, even for the pr...

In this paper, stabilizing control of tracked unmanned ground vehicle in 3-D space was presented. Firstly, models of major modules of tracked UGV were established. Next, to reveal the mechanism of disturbances applied on the UGV, two kinds of representative disturbances (slope and general disturbances in yaw motion) were discussed in depth. Consequently, an attempting PID method was employed to...

The paper presents simulation results of hybrid fuzzy logic with proportional plus conventional integral-derivative controller for the speed control of permanent magnet brushless dc (PMBLDC) motor. Although conventional PID controllers are widely used in the industry due to its simple control structure and ease of implementation, these controllers pose difficulties under the conditions of nonli...

This paper proposes to control the speed of the permanent magnet (PM) DC motor drive using fuzzy logic control (FLC) based on Matlab simulation environment. The proposed speed controller is developed based on fuzzy logic, to minimize maximum overshoot and steady state error. A comparison study and analysis of proposed fuzzy logic control to classical PID control system applied to PM DC motor is...

A kind of fuzzy-PID controller with adjustable factor is designed in this paper. Scale factor’s selfadjust will come true. Fuzzy control algorithm is finished in STEP7 software, and then downloaded in S7300 PLC. WinCC software will be used to control the change-trend in real time. Data communication between S7-300 PLC and WinCC is achieved by MPI. The research shows that this fuzzy-PID controll...

Application of fuzzy logic to the well known “ball on beam” motion control problem is reported. Comparison results indicate clearly superior performance of the fuzzy controller to that of the traditional PID controller. The process of control synthesis is summarised.
