用反模型法讲授用RLC电路构成的强迫阻尼振荡器
Teaching Forced Damped Oscillator Using RLC Circuit Through Inverse Modeling
摘要：
科学中的直接模型教学削弱了学生的学习过程，因为工程中的实际问题通常不是用直接模型来解决的，而是用逆模型来解决的。另一方面，在面向成形工程师的波与粒子物理课程中最相关的主题之一;它是简谐运动强迫阻尼的主题，其中许多物理现象可以解释为振荡强迫系统的品质因数Q和共振频率。为了吸引学生的注意力，并对这个问题进行应用。我们已经开发了一个实验装置，以采取测量电流，电压从电容器和电感器为不同的频率和电阻，一旦实验数据被收集，以研究电路内的电流的行为，并找出RLC参数与逆模型。最后，我们要详细展示系统的参数如何（电阻、电感和电容值）在这种系统中是非常相关的，从通过电压、电流和相移角的实验测量获得的结果来看，这是通过实施本文中描述的间接方法来实现的，因此，可以应用于更复杂系统的研究，例如电机，其中这些参数可能是未知的。
英文摘要：
Teaching by direct models in science has been weakening the learning process of the students, because the real problems in engineering are not solved by direct models instead commonly they are solved by inverse models. On the other hand, one of the most relevant topics in the course of waves and particle physics oriented for the forming engineers; it's the subject of simple harmonic motion forced damping, which many physical phenomena can be explained as the quality factor Q and the resonance frequency of an oscillatory forced system. In order to capture the attention of students and give an application to this issue. We have developed an experimental setup to take measurements of electric current, voltages from capacitor and inductor for different frequencies and resistances, once the experimental data were collected to study the behavior of the electrical current inside the circuit and find out the RLC parameters with an inverse model. Finally, we want to show the process in detail how parameters of the system (Resistance, Inductance and Capacitance values) are very relevant in this kind of systems, from the results obtained by experimental measurements of voltage, current and angle of phase shift, where this was achieved by implementing an indirect method described in this document, so that can be applied to studies of more complex systems such as a motor where such parameters may be unknown.
