Abstract
This paper studies on a new Hybrid Posicast Control (HPC) for Fundamental KY Boost Converter (FKYBC) worked in Continuous Current Mode (CCM). Posicast is a feed-forward compensator. It reduces the overshoot in the step result of the flippantly damped plant. But the conventional controller approach is sensitive owing to the changes in the natural frequency. So, as to reduce this undesirable sensitivity and load potential control of FKYBC, a HPC is designed in this article. Structure of HPC is posicast with feedback loop. The independent computational time delay is the main design function of the posicast. The enactment of the FKYBC with HPC is confirmed at various operating regions by making the MATLAB/Simulink and experimental model. The posicast function values are implemented in Arduino Uno-ATmega328P microcontroller. The results of new HPC have produced minimal noise in control signal in comparison with traditional PID control.
Highlights
A positive/negative DC source is important for most of the real-time applications such as audio amplifier, LED driver, the medical instruments, the mobile communications, the robot communication systems, the signal generator, central processing unit in Posicast Control (PC), and the data transmission interface devices
Simulation results and discussions of Fundamental KY Boost Converter (FKYBC) with Hybrid Posicast Control (HPC) and PID controllers are discussed in this part
It is evident that the FKYBC with HPC has produced null overshoots and quick settling times of 0.02 s, 0.017 s, and 0.016 s, respectively, whereas the same model with PID control had more overshoots of 22 V and settling times of 0.032 s, 0.03 s, and 0.028 s at different Vin
Summary
A positive/negative DC source is important for most of the real-time applications such as audio amplifier, LED driver, the medical instruments, the mobile communications, the robot communication systems, the signal generator, central processing unit in PC, and the data transmission interface devices. DC source is not directly taken from supply mains, and it is derived from the DC-DC converters. Based on this reasons, many DC-DC converters was designed such as Cuk, KY, and Luo converters (LC) [1,2,3,4]. Though the controller design is a challenging one for nonlinear damped dynamics of FKYBC that are functions of the load parameters, the new research in modern digital signal technology has recommended a new control to enhancing FKYBC regulation [5]
