| 摘 要： | 针对风力发电变桨系统的需求和永磁直流伺服电机的调速原理,对直流伺服驱动器的控制策略和控制电路进行了研究。在此基础上,研制了1台7.5kW的直流伺服驱动器,并进行了相应的实验研究。该驱动器在传统的双闭环直流调速系统和PI调节器的基础上,增加了转速前馈、电流前馈和死区补偿等动态校正补偿环节。实验结果表明了该控制策略的先进性,其中电流内环的带宽达到了350Hz,整个系统的动态响应也完全达到了风电变桨系统的要求。

| Abstract: | According to the requirements of pitch systems for wind turbine and the speed control principle of permanent magnet DC servo motor,the control strategy and control circuits of DC servo drive were studied.On the basis of the study,one 7.5 kW DC servo drive was developed and corresponding experiments was made.The 7.5 kW DC servo drive increased dynamic correction and compensation part such as speed feedforward,current feedforward,dead-space compensation and etc based on the traditional double closed-loop DC drive system and PI controller.The result of experiment indicates that the control strategy is advanced,of which the bandwidth of the inner current reached 350 Hz and the dynamic response of the overall system also meet the requirements of pitch system completely. |
