The fundamental problem of the power control for the driving of a dual-motor drive electric tracked vehicle is analyzed. The
tracked vehicle and its electric drive system are mathematically modeled. Power control schemes of the dual-motor drive system
is put forward, designed, and analyzed, including the distributed control system and the two control schemes speed-regulation
and torque-regulation. The field experiment shows that the two types of drive control schemes realize the driving function
of the vehicle feasibly and effectively. Obviously the comprehensive controller and two motors’ controllers are closely coupled
in the “speed-regulation” control scheme, in which they must coordinate very well to guarantee the control. Contrastingly,
in the “torque-regulation” control scheme, the comprehensive controller and two motors’ controller are not dependent closely
when the accuracy and response of the torque controlling is guaranteed. The latter is simpler and more practical than the
former. 相似文献

Tracked vehicle hybrid drive system is a kind of electromechanical transmission system and equipment. In order to improve the efficiency of system design and modeling, an automated modeling method was proposed for a series-parallel tracked vehicle hybrid drive systems. Based on the modeling of a power combining device and a power convergent device, the automated modeling principles were illustrated and the automated modeling rules and the screening conditions were further proposed. Then the final model equation eliminated intermediate quantity was derived. With the automated modeling method, some tracked vehicle hybrid drive systems were modeled in Simulink to validate the method. The automated modeling processes were programmed. And as an application demonstration for the automated modeling, optimal configuration seeking was described. The results show the method may build the model and screening the configuration automatically, which is a powerful method for rapid and automated modeling of tracked vehicle hybrid drive systems. 相似文献
