Research on PID Controlling of Servo System of Electronic Press Based on AMESim

根据AMESim软件快速实现动态系统的建模、仿真和分析等优点,利用AMESim软件对电子压力机伺服系统PID控制进行建模与仿真,并在仿真中对有无PID控制器的电子压力机系统进行对比。结果表明,通过改进控制算法,能有效提高PID控制的伺服系统稳态精度,调节时间短,超调小,可以克服非线性时变特性的影响。

According to the characteristics of the AMESim software as rapidly realizing dynamic system modeling, simulation and analysis, we can make use of the AMESim to be modeling and simu- lation of electronic press servo system on PID con- trol. in addition, Whether electronic press system with the PID controller in emulation are compared. Results shows that： the steady precision of servo system can be improved effectively by improving control algorithm. At the same time, the time - consuming and overstrike will be fewer, Beside, it also can overcome the impact of nonlinear time-- varying characteristic.
