A Comprehensive Multistage Average Controller for Trajectory Tracking in Solar‐Powered Mobile Robots: Analysis of Actuator‐Driver and Power Stage Integration

open access: yesInternational Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 224-246, June 2026.
ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies

Testing VIPV Curved Modules: Methods and Challenges

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 6, Page 744-757, June 2026.
This work presents procedures and equipment for characterizing curved vehicle‐integrated photovoltaic (VIPV) modules through STC I–V curve and relative angular response (RAR) measurements. Outdoor measurements are compared with indoor measurements obtained using a collimated‐light solar simulator, showing excellent agreement for STC I–V curves.

Political Cycles, Electricity Policy, and Mexico's Economy

open access: yesLatin American Policy, Volume 17, Issue 2, June 2026.
ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...
