伺服压力机机械负载模拟系统的设计
Design of the Mechanical Loads Emulation for Servo Press

搭建了整套伺服控制的软硬件系统。为了对伺服压力机的传动系统设计和控制进行优化，构建了一种用伺服电机模拟机械负载动力学特征，以模拟伺服非线性机械负载动力学特征的伺服压力机负载的模拟实验平台。该实验平台采用前馈与转速跟踪结合实施控制，以伺服电机作为可调控柔性负载等效于各种机械负载下的输出，在实验室环境下实现对于各种机械负载的模拟。由于规避了逆动力学特性的引入，本系统具有比以往测功机更好的动态响应特性。
The whole system including software and hardware is constructed in this paper. In order to realize the optimization design and control for servo press, a servo press mechanical loads emulation experimental platform using servo motor to emulate the dynamic characteristics of different mechanical loads is constructed. The experimental platform which uses feedforward control combined with speed-tracking control in design can realize the emulation of different mechanical loads in laboratory environment based on the flexible control of servo motor by realizing the servo motor load equivalent to different mechanical loads. It is expected that the system might have better dynamic response than the ordinary dynamometer as it avoids introducing the inverse dynamic control
