摘　　要：为实现电机-变速器一体化传动换挡过程的优化控制,开发了其试验台架的测试与控制系统。针对一体化传动换挡过程的特点和功能需求,测控系统采用了上下位机的结构形式。上位机在NI-Labview环境下进行软件功能的设计和控制算法的实现;下位机利用其实时操作系统测量换挡过程的关键信号并输出控制指令。换挡控制采用了分阶段、多目标的协调控制算法,以提高换挡品质。大量换挡试验表明,该测控系统性能稳定,能实现信号的同步采集、数据储存、实时显示、换挡控制和在线调参等功能,为换挡过程建模和控制策略优化提供依据。For achieving the optimal control for the shift process of integrated motor-transmission （IMT） , a measurement and control system of test bench is developed. In view of the functional requirements and the distinc- tions of shifting process of IMT, an upper and lower computer structure is adopted for the system, in which the up- per computer fulfils the tasks of software function design and control algorithm implementation with NI-Labview, while the lower computer with real-time operating system measures the key signals of shift process and sends out the control instructions. The shift control adopts a phase-wise multi-objective coordinated control algorithm for improving shift quality. The results of numerous shifting tests show that the system is stable in performance and can fulfill the functions of synchronous signals acquisition, data storage, real-time display, shift control and on-line parameter ad- justment, providing a basis for the modeling and control strategy optimization of shift process.
