【摘要】：純電動汽車電源性能測試平臺是研究電動汽車綜合性能的必備條件。為研究純電動汽車電源性能,提出由直流電機-飛輪組成的車載電源性能測試方案,直流電機用來模擬電動汽車驅(qū)動電機,飛輪用來模擬電動汽車的負(fù)載和慣量。建立了驅(qū)動電機直流調(diào)速系統(tǒng)的控制模型,運用Simulink和Psim軟件對驅(qū)動電機的直流調(diào)速系統(tǒng)進(jìn)行聯(lián)合仿真,分析并比較了PID控制和模糊-PID控制兩種控制策略下驅(qū)動電機的直流調(diào)速效果;建立了基于dSPACE的車載電源性能測試硬件在環(huán)測試平臺,以簡單循環(huán)工況為直流調(diào)速系統(tǒng)的參考轉(zhuǎn)速,通過實驗對兩種控制策略下的仿真結(jié)果進(jìn)行了實驗驗證。仿真和實驗結(jié)果均表明模糊-PID控制策略在控制精度和動態(tài)性能方面優(yōu)于PID控制策略。
[Abstract]:Pure electric vehicle power performance test platform is a necessary condition to study the comprehensive performance of electric vehicle. In order to study the power performance of pure electric vehicle, an on-board power performance test scheme composed of DC motor and flywheel is proposed. The DC motor is used to simulate the driving motor of electric vehicle, and the flywheel is used to simulate the load and inertia of electric vehicle. The control model of DC speed regulation system of driving motor is established, and the joint simulation of DC speed regulation system of driving motor is carried out by using Simulink and Psim software. This paper analyzes and compares the DC speed regulation effect of the drive motor under two control strategies: PID control and fuzzy-PID control. A hardware in loop testing platform of on-board power supply performance testing based on dSPACE is established. The reference speed of DC speed regulating system is under simple cycle condition. The simulation results under two control strategies are verified by experiments. The simulation and experimental results show that the fuzzy PID control strategy is superior to the PID control strategy in terms of control accuracy and dynamic performance.
