Abstract

Purpose

The purpose of this study is to stabilize the rotating speed of the permanent magnet direct current (PMDC) motor driven by a DC-DC boost converter under mismatched disturbances (i.e.) under varying load circumstances like constant, frictional, fan type, propeller and undefined torques.

Design/methodology/approach

This manuscript proposes a higher order sliding mode control to elevate the dynamic behavior of the speed controller and the robustness of the PMDC motor. A second order classical sliding surface and proportional-integral-derivative sliding surface (PIDSS) are designed and compared.

Findings

For the boost converter with PMDC motor, both simulation and experimentation are exploited. The prototype is built for an 18 W PMDC motor with field programmable gate arrays. The suggested sliding mode with second order improves the robustness of the arrangement under disturbances with a wide range of control. Both the simulation and experimental setup shows satisfactory results.

Originality/value

According to software-generated mathematical design and experimental findings, PIDSS exhibits excellent performance with respect to settling speed, steady-state error and peak overshoot.

用于永磁直流电机直流-直流升压转换器系统的新型高阶滑动模式控制，探索不匹配干扰

本研究旨在稳定直流-直流升压转换器驱动的永磁直流（PMDC）电机在不匹配干扰（即）恒定、摩擦、风扇类型、螺旋桨和未定义扭矩等不同负载情况下的转速。设计并比较了二阶经典滑动面和比例-积分-派生滑动面 (PIDSS)。利用现场可编程门阵列为 18 W PMDC 电机制作了原型。所建议的二阶滑动模式提高了该装置在干扰下的鲁棒性，控制范围更广。根据软件生成的数学设计和实验结果，PIDSS 在平稳速度、稳态误差和峰值过冲方面表现出卓越的性能。
