In recent years, electromagnetic and electronically controlled shock absorbers, as well as regenerative suspension systems, have been actively developed. The use of such shock absorbers allows for energy recovery and active damping of vibrations, but a significant drawback of existing electromagnetic damping systems is the lack of effective electronic control systems. The purpose of this work is to develop and study an adaptive information and control system for damping oscillations in a regenerative electromagnetic suspension.

An electromagnetic shock absorber-generator converts the mechanical linear movement of the piston into an electromotive force, and its magnitude is directly proportional to the speed of the shock absorber rod. The shock absorber's resistance force is proportional to the electric current output by the generator. By regulating the current drawn from the generator using an information and control system based on pulse-width modulation (PWM) of electrical energy parameters, it is possible to change the resistance force of the shock absorber and obtain an automatically controlled adaptive suspension. Modern electronics allow you to quickly (~ 0.1 ms) change the suspension resistance coefficient by adjusting the PWM signal duty cycle. Based on the above, the principles of building an adaptive information and control system for damping the oscillations of a regenerative electromagnetic suspension have been formulated. These principles include: obtaining the required shock-absorbing characteristic by regulating the power taken away in accordance with the identified patterns; in the conversion of mechanical vibration energy into electrical energy, with the possibility of its subsequent use, for example, for charging a battery, while maintaining the damping characteristics of the shock absorber; in the possibility of changing the shock absorber characteristics in a short time (~ 0.1 ms), including in automatic mode. The information and control system for damping oscillations includes a circuit for determining the sign of the input voltage, a circuit for extracting the module of the input signal, a shock absorber characteristic generator, and a PWM driver circuit. The most important task solved in this work is the possibility of quickly changing the parameters of a regenerative electromagnetic suspension depending on the operating conditions, as well as the possibility of energy recovery. The results of the study can be used to build systems for damping the vibrations of vehicles and electronic equipment.
