The development of an injection molding machine with a force control response is challenged. In this research, first, although the ejection axis of a ball screw drive produces the pressure error by vibration and nonlinear friction of a machine resonance system, this pressure error is oppressed by new friction compensation and oscillating inhibitory control. Such technology is applied to the same ball screw drive as an ejection axis, and the proposed force control system which realizes a next-generation high performance electric injection molding machine is constituted. Next, this research realizes the pressure control based on 1 KHz force sensing. It is impossible for the conventional injection molding machine to realize 1 KHz force sensing base force control. By using the high-speed sampling of FPGA, this research realizes the proposed friction free high order disturbance observer and the force control response based on 1-kHz force sensing. Moreover, its validity is verified.

具有力控制响应的注塑机的开发受到挑战。在本研究中，第一，虽然滚珠丝杠传动的顶出轴产生的机械共振系统的振动和非线性摩擦的压力误差，这种压力误差被抑制新的摩擦补偿和振荡抑制控制。将该技术应用于与射出轴相同的滚珠丝杠驱动，构成了实现下一代高性能电动注塑机的力控制系统。其次，实现了基于1KHz力传感的压力控制。 传统的注塑机不可能实现1KHz的力传感基础力控制。利用FPGA的高速采样功能，实现了无摩擦高阶扰动观测器和基于1 kHz力传感的力控制响应。并验证了其有效性。
