【摘要】 传统阶跃响应法在张力控制系统调试中易产生超调，导致传动链断裂或材料形变等安全隐患，为解决该难题，提出一种基于冲激函数的安全激励方法，可在避免系统振荡超调的情况下将脉冲序列响应拟合成阶跃响应曲线。对拟合得到的响应函数进行拉普拉斯变换，从而导出系统的数学模型。在此基础上，进一步设计了控制器，实现了对收放卷张力系统的精确控制。由实验结果可见，系统无超调，调节时间较短，控制效果显著。更多还原

【Abstract】 The traditional step response method is prone to overshoot in the tension control system debugging, which may lead to safety hazards such as transmission chain breakage or material deformation. This paper proposes a safe excitation method based on the impulse function, which can fit the pulse sequence response into a step response curve without causing system oscillation and overshoot. The Laplace transform of the fitted response function is conducted to derive the mathematical model of the system. On this basis, a controller is further designed to achieve precise control of the tension system in the winding and unwinding process. The experimental results show that the system has no overshoot, a short adjustment time, and a significant control effect.更多还原
