Versions Notes
The journal retracts the article, A Closed-Loop Control Mathematical Model for Photovoltaic-Electrostatic Hybrid Actuator with a Slant Lower Electrode Based on PLZT Ceramic [1], cited above. Following publication, the authors contacted the Editorial Office regarding mathematical model and data errors. During a review, the authors found that there was a major error in the photovoltage mathematical model of Equation (2), and that the error led to serial errors in the close-loop control mathematical model, method, and simulation results shown in Table 2, Table 3, and Figures 7−9. Consequently, the results and conclusions were substantially impacted, and it was decided that a correction would not be appropriate. Adhering to journal policy, an investigation was conducted that confirmed the error reported by the authors. Thus, the article [1] will therefore be retracted.
This retraction was approved by the Editor-in-Chief of the journal Actuators.
The authors agreed to this retraction.
