The invention discloses a magneto-rheological damper energy management control system based on a photovoltaic power generation system, and the system comprises a main circuit, a sampling circuit, an amplitude limiting and filtering conditioning circuit, an auxiliary power supply, a control circuit, and an isolation circuit and driving circuit. The main circuit mainly consists of a photovoltaic cell panel, a first Buck, a storage battery, a second Buck and a magneto-rheological damper, wherein the photovoltaic cell panel serves as a power supply unit which supplies power to the storage battery and the magneto-rheological damper. The sampling circuit collects the output voltage and output current of the photovoltaic cell panel, an end voltage of the storage battery, the output current of the first Buck and the output voltage and output current of the magneto-rheological damper, and transmits the above voltages and currents to the amplitude limiting and filtering conditioning circuit for signal processing. The signals are amplified through the isolation circuit and driving circuit, so as to drive the power switching tubes in the first Buck and the second Buck to be turned on or turned off. The auxiliary power supply is used for supplying power to the control circuit.
Description
technical field [0001] The invention relates to a magnetorheological fluid damper (MRFD for short) energy management control system based on a photovoltaic power generation system, which solves the energy flow relationship of the circuit, enables the system to operate efficiently and stably, and is used for power supply for loads requiring current similar to MRFD. Background technique [0002] In order to reduce the resistance against hurricanes and earthquakes, it is necessary to add MRFD to the building. Since the control of the magnetic field in MRFD can be obtained by controlling the excitation current, the control power supply system of MRFD must be able to accurately adjust its current. Currently, the DC power system used for MRFD needs to be connected to the power grid to provide continuous and controllable current to the MRFD. If the MRFD is working away from the power grid or it is difficult to obtain power, the power system cannot provide the required current to the...
