This paper deals with the design of suitable control strategy for a dual input DC/DC converter. Nowadays, it becomes very essential to stabilize the output voltage of DC/DC converter for hybrid energy application. To achieve this objective, control of duty ratios of switches using different control strategies is proposed in this paper. Comparative analysis has been carried out between two control...
This paper presents an Active Disturbance Rejection Control (ADRC) technology and PI-fuzzy compound technology method for Active Power Filter (APF). The ADRC consists of Tracking Differentiator (TD), Extended State Observer (ESO) and Nonlinear State Error Feedback law (NLSEF). This control method makes full use of the error driven control law, the modern control theory and the nonlinear feedback control...
This thesis presents historical background of fuzzy control and fundamentals of TSC reactive power compensator. It is designed with dual-input of voltage deviation and reactive power deviation, and output fuzzy control system of class number of TSC switches. The system is divided into two groups according to different membership functions, the first group using triangle membership function and the...
Distribution STATCOM (D-STATCOM) is a custom power device connected in parallel to power system. In this paper, Neuro-Fuzzy Controller (NFC) which has robust structure is proposed for control of D-STATCOM's dq-axis currents. Designed NFC is first order Mamdani type NFC structure and has two inputs, one output and six layers. D-STATCOM is based on three-level cascaded inverter and this inverter is...
This paper proposes a novel regenerative braking control system of electric wheelchairs for senior citizen. ldquoElectric powered wheelchairrdquo, which generates the driving force by electric motors according to the human operation, is expected to be widely used as a mobility support system for elderly people. This study focuses on the braking control to realize the safety and smooth stopping motion...
In this paper, with analyzing the existing questions of conventional nine-area voltage and reactive power integrated control method, a new fuzzy control logic based dynamic reactive power boundary substation voltage and reactive power integrated control method is proposed. The fuzzy logic control strategies of this method can finish the decoupling control of voltage and reactive power in tight coupled...
This paper studies the operation of a multi-input boost converter powered by photovoltaic modules. Performance of ripple correlation control (RCC) and fuzzy logic control in tracking maximum power point are investigated through simulation. Both single panel operation and dual panel operations are analyzed to prove that they are controlled independently. A simple analog circuit implantation is tested...
