最近，许多塑料制品被生产和使用。这些塑料产品大多是用注塑机制造的。塑料制品的质量取决于注塑力。因此，开发一种精细的力控制系统是十分重要的。通常，在力控制系统中，来自环境的力信息由力传感器检测。然而，使用力传感器的控制系统存在与信号噪声、传感器成本、窄带宽和其他因素相关的问题。为了克服这些问题，本文提出了一种利用反力观测器的无传感器力控制方法。使用滚珠丝杠的注塑机，其共振频率受扭转现象的影响。这种新的反力观测器考虑了扭转现象和摩擦现象。
Recently, many plastic products have been produced and used. These plastic products are mostly manufactured using injection molding machines. The quality of plastic products depends on the injection force. Therefore, it is important to develop a fine force-control system. Generally, in force-control systems, the force information from the environment is detected by a force sensor. However, control systems using force sensors present problems related to signal noise, sensor cost, narrow bandwidth, and other factors. To overcome these problems, this paper presents a proposal for a new sensorless force-control method using a reaction torque observer. The injection molding machine, which uses a ball screw, has a resonance frequency that is affected by the torsion phenomenon. This new reaction torque observer considers the torsion phenomenon and friction phenomena.
