This paper describes the design and implementation of simple fuzzy logic controller (SFLC) for a nonlinear quasi-resonant converter (QRC). It is shown that the two-dimensional rule table of conventional FLCs (CFLCs) used in power converters can be reduced to one-dimensional rule table using SFLC. The proposed SFLC reduces the memory space and computing time of the fuzzy algorithm. The tuning of scaling factors and the generation of fuzzy rules are also easier when compared with CFLC. As a result, realizing SFLC in a Microcontroller or Digital Signal Processor (DSP) is made simple. The proposed controller structure is universal and it can be directly applied to any of the dc–dc converter topologies. In this paper, the application of SFLC is successfully verified for the voltage control of Extended Period (EP)-ZCS/ZVS-QRC through simulation and experimental studies using TMS320F2407A Processor. The ability of SFLC, compared to CFLC, to achieve good transient response for load variations and supply disturbances is demonstrated.

Nowadays, renewable energies have been widely applied to achieve eco friendly objectives. This paper presents the development of a single-phase grid-connected wind energy generation with the improvement in power quality and efficiency. This mainly focuses on showing the improvement in power quality by overcoming the drawbacks with the existing wind energy generation based on the PLL with the discrete PI controller. It is found that Total Harmonic Distortions (THD) present in PLL Single-phase grid-connected wind energy generation can be reduced by using modified PLL method. The modified wind energy generation is based on PLL with Fuzzy logic controller instead of PLL with discrete PI controller. The PLL gets input from the load side, and compare with any one parameters current or voltage (closed loop system). The aim of this survey is to propose a new topology in (HCM) HILL CLIMB METHOD. The tasks related to the SVPWM algorithm, the PLL, the MPPT algorithm, and the monitoring of the DC voltage were successfully implemented in the DSC. Keywords – Total Harmonic Distortions, Phase Locked Loop, Discrete PI Controller, Fuzzy logic controller, Space Vector Pulse Width Modulation, Maximum Power Point Tracking, Digital Signal Controller.

This project studies temperature control using a microprocessor with an interfacing circuit. This type of control is studied theoretically and a circuit is designed and implemented by using a software program for a hospital building in Kirkuk city by choosing nearly 10 rooms. The program is written with the reference temperature using an Lm35 sensor that is suitable for this work, where it operates over a T range from 55 to 150, by entering machine code to the Microprocessor 8085 to collect data from sensors in the form of analog values, changes it to digital vales by Analog to Digital Converter, and enters it into the microprocessor. The Microprocessor 8085 takes data from sensors that has been changed to a digital signal by Analog to Digital Converter to receive to fuzzy logic controller, which is the best way in which this type of precision control can be accomplished by controller. Here we try to control the temperature of the system using the fuzzy logic controller from the data coming from the Microprocessor 8085. The Microprocessor 8085 has been selected because the error rate is very low and the results are very accurate.

This paper invests in FPGA technology to control the speed of an autonomous car using fuzzy logic. For that purpose, we propose a co-design based on a novel fuzzy controller IP. It was developed using the hardware language VHDL and driven by the Zynq processor through an SDK software design written in C. The proposed IP acts according to the ambient temperature and the presence or absence of an obstacle and its distance from the car. The partitioning of the co-design tasks divides them into hardware and software parts. The simulation results of the fuzzy IP and those of the complete co-design implementation on a Xilinx Zynq board showed the effectiveness of the proposed controller to meet the target constraints and generate suitable PWM signals. The proposed hardware architecture based on 6-LUT blocks uses 11 times fewer logic resources than other previous similar designs. Also, it can be easily updated when new constraints on the system are to be considered, which makes it suitable for many related applications. Fuzzy computing was accelerated thanks to the use of digital signal processing blocks that ensure parallel processing. Indeed, a complete execution cycle takes only 7 us.

This paper presents interval type-2 fuzzy logic (IT2FL) controller applied on a direct torque controlled (DTC) permanent magnet synchronous motor (PMSM), using digital signal processing (DSP). The simulation of PMSM with space vector pulse widths modulation (SVPWM) inverter presented under several operating condition. To verify the simulation results a hard ware setup is prepared and tested at several operating conditions using dspace 1102 DSP model.  The experimental and simulation results are in agreement and the torque dynamic response is very rapid and the system achieves the steady state in a very short time.

This paper describes the design and implementation of a heliostat orientation control system based on a low-cost microcontroller. The proposed system uses a fuzzy logic controller (FLC) with the Center of Sums defuzzification method embedded on a dsPIC33EP256MU806 Digital Signal Processor (DSP), in order to modify the orientation of a heliostat by controlling the angular position of two DC motors connected to the axes of the heliostat. The FLC is compared to a traditional Proportional-Integral-Derivative (PID) controller to evaluate the performance of the system. Both the FLC and PID controller were designed for the position control of the heliostat DC motors at no load, and then they were implemented in the orientation control of the heliostat using the same controller parameters. The experimental results show that the FLC has a better performance and flexibility than a traditional PID controller in the orientation control of a heliostat.

This paper aims to study for accurate sheet trim shower position for paper making process. An accurate position is required in an automation system. A mathematical model of DC motor is used to obtain a transfer function between shaft position and applied voltage. PID controller with Ziegler-Nichols and Hang-tuning rule and Fuzzy logic controller for controlling position accuracy are required. The result reference explains it that the FLC is better than other methods and performance characteristics also improve the control of DC motor.
