建立了直流伺服电机拖动系统的机电系统模型.基于该模型,在MATLAB中,对无控制策略和采用PID控制策略的拖动系统分别进行仿真.仿真结果表明:无控制策略的拖动系统在响应时间、准确性和稳定性上存在不足;而引入PID控制器后,系统的响应时间缩短为2s,超调量几乎为零,输出稳定在理想值附近,满足了拖动系统对"快"、"准"、"稳"的要求,且应用该控制策略,无需提高直流伺服电机性能,而能够大大改善拖动系统的机械特性和负载能力.
建立瞭直流伺服電機拖動繫統的機電繫統模型.基于該模型,在MATLAB中,對無控製策略和採用PID控製策略的拖動繫統分彆進行倣真.倣真結果錶明:無控製策略的拖動繫統在響應時間、準確性和穩定性上存在不足;而引入PID控製器後,繫統的響應時間縮短為2s,超調量幾乎為零,輸齣穩定在理想值附近,滿足瞭拖動繫統對"快"、"準"、"穩"的要求,且應用該控製策略,無需提高直流伺服電機性能,而能夠大大改善拖動繫統的機械特性和負載能力.

It establishes an electro-mechanical model of DC servo motor drive system,makes simulation in Matlab with uncontrol strategy and PID controller.The simulation results show that system with uncontrol strategv has three shortcomings on stability,rapidity and accuracy while the response time of the system in PID controller shortened to two seconds,and the output stabilize at an ideal value.It satisfies the drive system reauirements of stability,rapidity and accuracy,can greatly improve the mechanical properties of the drive svstem and driving capacity without improving performance of DC salvo motor.
