To improve the isolation effect of the quasi zero stiffness magnetic levitation isolation platform and reduce the negative impact of vibration signals generated by the vibration source on the isolation object, an active hybrid control system for the quasi zero stiffness magnetic levitation isolation platform is optimized and designed. Modify sensors, power amplifiers, and drive equipment, adjust the controller to active hybrid mode, adjust the connection method of the system circuit, and complete the design of the control hardware system. Simulate the working process of a quasi zero stiffness magnetic levitation isolation platform, and detect the vibration status of the isolated object on the platform through platform data acquisition, feature extraction, and feature matching. Measure the real-time electromagnetic force of the quasi zero stiffness magnetic levitation isolation platform under vibration conditions, as the initial value for platform control. With the support of electromagnetic theory, the active hybrid control function of the magnetic levitation isolation platform is achieved from both active and hybrid aspects through the calculation of electromagnetic force and current control quantities. The experimental results show that after the application of the active hybrid control system, the vibration amplitude and frequency attenuation rate acting on the isolated object in the quasi zero stiffness magnetic levitation isolation platform have increased by 62.34% and 32.005%, respectively. It has obvious advantages in the control effect of quasi zero stiffness magnetic levitation isolation platform.
