Control method and device of sequential supercharging system, storage medium and electronic equipment

The invention provides a control method and device of a sequential supercharging system, a storage medium and electronic equipment, and the method comprises the steps that the gas compressor inlet pressure of a controlled supercharger is obtained, and the gas compressor inlet pressure is the gas pressure of the upstream of a gas compressor of the controlled supercharger; under the condition that the pressure of the inlet of the gas compressor jumps between a positive value and a negative value within the first preset duration, it is determined that the current operation state of the controlled supercharger is an unstable state, and the unstable state is the state that the controlled supercharger is switched between opening and closing; and under the condition that the current operation state of the controlled supercharger is an unstable state, the controlled supercharger is forcibly started. According to the method, whether the sequential supercharger is in a back-and-forth switching abnormal state or not is
