Dynamic model and control strategies development of a rigid-flexible manipulator robot are presented in this paper. Dynamics, generated using Hamilton's principle, are highly non-linear and complex. Then the obtained model becomes linearized around a chosen operating point for the system. Two different strategies of control are applied to the rigid-flexible manipulator for the vibration suppression...
In this paper, real-time position control of rotary servo system is performed by using fuzzy logic. SRV-02 DC servo system produced by Quanser is equipped with a DC motor. Servo system is loading by using various metallic weights and performance analysis are made according to international performance criteria. When making comparison of performance, it is seen that controller which is designed via...
Autonomous Underwater Vehicle (AUV) is a typical system which is characterized by nonlinearity, uncertainty of system parameters, and it is also affected by many external disturbances. Therefore, it is difficult to achieve the accurate AUV motion control, which includes depth control, heading control and so on. In order to improve the stability and robustness of depth control system of AUV, this paper...
We propose a hybrid fuzzy PID control system to prevent overshoot and oscillations in DC-DC buck-boost converter for solar-battery system. We designed and simulated a PID, a Fuzzy logic controller, and a hybrid fuzzy PID control system to stabilize the output voltage of the buck-boost converter. The performance results using dynamic response parameters of these controllers such as rise time, overshoot,...
Flow control is essential in many industrial applications such as chemical reactors, heat exchangers and distillation columns. Most industrial processes exhibit nonlinearities and inherit dead time, which limit the performance of conventional PID controllers. This Project is about the design and implementation of Fuzzy Logic Controller (FLC) for flow control applications. The objective is to overcome...
Reducing the fuel consumption of road vehicles has the potential to decrease environmental impact of transportation as well as achieve significant economical benefits. This paper proposes a novel methodology for improving the fuel economy of vehicle fleets via learning fuel-efficient driving behaviors. Vehicle fleets composed of large number of heavy vehicles routinely perform runs with different...
This paper presents the performance of hybrid fuzzy controller in response to several different threshold values. The hybrid-fuzzy consists two control strategies i.e. a PID-type fuzzy logic controller and an incremental PID action. At the early stage of control action, the task is handled by PID-type fuzzy controller. When the absolute of error is less than threshold value, the input of integrator...
In this study position and vibration control of a rigid-flexible robot manipulator is investigated. Initially dynamic model of the manipulator system is obtained by using Lagrange equations and assumed modes method. Two adaptive networks based fuzzy logic controllers (ANFLCs) are proposed for tracking control of the rigid link and the flexible link. The training and testing data of ANFLCs are obtained...
The increased complexity of the dynamics of robots manipulator considering joint elasticity makes conventional model-based control strategies complex and difficult to synthesize. This paper presents investigations into the development of composite collocated proportional-derivative (PD) and Fuzzy Logic Control for trajectory tracking and vibration control of a flexible joint manipulator respectively...
In this paper we present a fuzzy logic control approach designed to stabilize a multi-input multi-output magnetic suspension system. The system has four cubic floaters and four actuators that apply magnetic forces on the floaters, the suspension is performed by changing the voltages applied on the actuators, hence changing their currents, producing vertical magnetic forces that balance with the gravitational...
For motion controlling switched reluctant motor (SRM) directly-driven hydraulic system, a self-tuning dead-zone compensation fuzzy controller is put forward to compensate the dead-zone characteristics of SRM in the paper. The proposed controller is simulated and experimental Study on the proposed controller is carried out on the directly-driven hydraulic system. The results show that the SRM directly-driven...
