The variability of renewable energy sources(RESs)and load demand variations may lead to power alternations in converter control actions,potentially compromising stability and reliability and posing operational security risks,particularly in islanded microgrids.To address these challenges,this research introduces an innovative optimal control approach structured around a reformulated version of the Bolza problem.A variational control methodology is employed to ensure regularity,with boundary conditions derived to optimize power tracking and frequency control at nodes.Additionally,a solution dimension reduction technique leveraging the augmented Bolza problem is proposed to efficiently approximate the optimal control solution.The effectiveness of the proposed control methodology is validated through MATLAB/Simulink simulations by comparing the novel augmented Bolza-based control approach with conventional methods from the literature,namely Model Predictive Control(MPC)and Pontryagin's Minimum Principle(PMP).A real-time hardware-in-the-loop experimental test is conducted to validate the superiority of the proposed methodology. 展开更多

This paper describes the orbit design of the deployable payload Rover 2 of MINERVA-II,installed on the Hayabusa2 spacecraft.Because Rover 2 did not have surface exploration capabilities,the operation team decided to experiment with a new strategy for its deployment to the surface.The rover was ejected at a high altitude and made a semi-hard landing on the surface of the asteroid Ryugu after several orbits.Based on the orbital analysis around Ryugu,the expected collision speed was tolerable for the rover to function post-impact.Because the rover could not control its position,its motion was entirely governed by the initial conditions.Thus,the largest challenge was to insert the rover into a stable orbit(despite its large release uncertainty),and avoid its escape from Ryugu due to an environment strongly perturbed by solar radiation pressure and gravitational irregularities.This study investigates the solution space of the orbit around Ryugu and evaluates the orbit’s robustness by utilizing Monte Carlo simulations to determine the orbit insertion policy.Upon analyzing the flight data of the rover operation,we verified that the rover orbited Ryugu for more than one period and established the possibility of a novel method for estimating the gravity of an asteroid. 展开更多
