Photovoltaic (PV) inverters are now supposed to provide additional supporting services with more reliability and efficiency. This paper presents three different control methods for generating reference current in a multifunctional, multilevel grid-tied PV inverter for harmonic, reactive, and unbalance compensation. These methods are the synchronous reference frame (SRF) theory (d-q), the instantaneous reactive power (IRP) theory (p-q), and the conservative power theory (CPT). As a result, the primary goal is to propose a low-cost multifunctional solar invert for distributed generation, with an appropriate prototype developed in the laboratory for experimental validation of various modes of operation. Demonstrated results show that the presented inverter is capable of providing various ancillary services with all three types of control.

Indonesia is one of the developing countries in the industrial sector. Many industrial equipment that utilizes an electric motor to run the system. In running the system using an electric motor, it is necessary to adjust the speed of the electric motor as needed. The 3-phase induction motor is one type of electric motor that has a strong, inexpensive, and high-efficiency construction, so it is often used in industry. However, setting the speed and torque of an induction motor is not easy to do. Setting the frequency of the induction motor voltage can be done using an inverter, therefore a single phase inverter can be used to adjust the speed of a three phase induction motor. In regulating the speed of the induction motor, a control is needed to keep the speed constant as needed. In this study, a 3-phase induction motor speed regulation system was simulated using an inverter controlled by a Fuzzy Logic Controller (FLC). Based on the research that has been done, it can be seen that the Fuzzy Logic Controller (FLC) is able to regulate the speed of a 3-phase induction motor with an error of 0.25%

“…TLBO outperformed many other rigorous optimization techniques due to the absence of any tunable gains and weighting factors. Recently, many different evolutionary algorithms have been used, which include the gravitational-search algorithm [18]− [21], grey wolf optimizer [22]− [24], and artificial bee colony algorithm [25]− [27]. This paper optimizes the HDV speed controller's proportional-integral (PI) gains (KP and KI) to achieve better accurate reference tracking performance under variable drive cycles.…”

In internal combustion engines, adjusting the air-fuel ratio is essential to control the speed and minimize the burnt fuel. The throttle opening is the actuator to control the air-fuel. A better design for the used/conventional controller can give a better response without additional cost. In this work, the proposed controller gains of the proportional-integral (PI) controller are tuned to enhance the speed in constant and variable drive cycle modes. The tuning process is conducted based on two of the most efficient performance indices used in this field. The performance indices are integral absolute error (IAE) and integral time absolute error (ITAE). The optimization problem is solved using three reliable stochastic optimization algorithms to ensure mature convergence of the solutions, to avoid local optima solutions, and to ensure effective shrinking of the search space. The optimization algorithms are teaching-learning-based optimization (TLBO), particle swarm optimization (PSO), and genetic algorithm (GA). Different simulations are conducted to validate the results. The results are compared with conventional tuning methods regarding the system's time response.
