Rapid Control Prototype Development of Dual-Motor Drive Electric Tracked Vehicle

为引入快速控制原型方法以有效指导电传动履带车辆双侧驱动控制策略开发,推导出不同工况下双侧电机转子轴端转动惯量匹配及阻力矩公式,并提出台架试验方案.在Matlab/Simulink环境下开发了转速调节与转矩调节控制原型模型;依托电传动双路试验台架和dSPACE系统,构建适合电传动履带车辆双侧驱动快速控制原型试验台架.对两类控制策略进行快速完善、验证和比较,获得较优的双侧驱动控制策略原型.结果表明,采用快速控制原型与试验台架相结合的方法可提高控制策略开发效率.

Rapid control prototyping（RCP） method is introduced and applied to the dual-motor drive control strategy of electric tracked vehicle, and equations of inertial and resistance torque executed on motors＇ rotor shaft are deduced. Method of bench experiment is proposed. RCP models of speed- regulation and torque-regulation are built up in a Matlab/Simulink environment. Based on dual line electric drive test bench and dSPACE, electric tracked vehicle dual-motor driving control strategy RCP bench is properly constructed. Speed-regulation and torque-regulation control prototype is improved, validated and compared rapidly, and an optimal control strategy prototype is finally obtained. It showed that the method of combining RCP and test bench promotes the efficiency of control strategy development.
