Abstract

To enhance the stability, reliability, and efficiency, reduce the operation cycle time, and augment the operation security capability of fully electric and intelligent military special vehicles, a novel segmented pseudo-differential feedback (PDF) control algorithm for the permanent magnet synchronous motors (PMSMs) of special vehicles is introduced. The control algorithm optimizes the differential part of the control system and avoids the direct differential calculation. This enhances the dynamic response and anti-interference capability of the control system, ensuring a rapid and robust performance. At the same time, the control system parameters are determined based on the error and the rate of change of the error in a segmented manner, ensuring precise control of specialized vehicles under various operating conditions. To verify the effectiveness of the proposed control algorithm, a simulation model is established for simulation analysis; an experimental platform is built for experimental verification. Both simulation and experimental results demonstrate that the proposed control algorithm exhibits notable advantages, including a rapid output response, and the absence of overshoot and oscillation. These characteristics effectively enhance the motor efficiency, optimize the output attributes, and elevate the overall operational performance of electric special vehicles.
