Digital twin in simulation environment MARS

The article considers a technique for constructing a digital twin to simulate the aging processes of electrical circuit components and associated gradual equipment failures. This twin is created by means of I/O boards connected to the STM 32 microcontroller. This allows you to transfer some analog signal from the object and digitize it in the microcontroller, which is then transferred to a computer running the MARS simulation environment on it. The other channel implements the same signals, but from the computer model of the object and further, the signals from the computer model and from the real object are compared using a comparator, and then visualized using a virtual oscilloscope. The hardware-software implementation of the digital twin is given. Goal: implement a digital twin of a rectifier with a filter in the MARS simulation environment.
