Problems solved by technology
However, due to the strong dynamic coupling relationship between the linear vibration motor and the touch suspension structure, in practical applications, the equivalent parameters of the linear vibration motor are obtained based on the single motor simulation test. When using the equivalent parameters When simulating and modeling the touch suspension system of a linear vibration motor, there is often a deviation between the simulated system response frequency response curve and the actual structural frequency response curve, which reduces the simulation accuracy of the subsequent linear vibration motor short signal

The embodiment of the invention provides an equivalent parameter correction method and system for a touch suspension system with a linear vibration motor, a medium and electronic equipment. An actualfrequency response curve of an actual touch suspension system with a linear vibration motor is used as a reference standard; according to a simulation frequency response curve of the touch suspensionsystem with the linear vibration motor, the equivalent parameters are corrected in a sectional mode, accurate simulation parameters are provided for simulation modeling of the touch suspension systemwith the linear vibration motor, so that the simulation frequency response curve is close to an actual frequency response curve as much as possible, and the simulation precision of short signals of the linear vibration motor is improved.
Description
【Technical field】 [0001] The invention relates to the technical field of control, in particular to a suspension system equivalent parameter correction method, system, medium and electronic equipment. 【Background technique】 [0002] Linear vibration motor (LRA) has become the mainstream haptic feedback solution in mid-to-high-end mobile phones. However, the application on touch display devices such as automobiles is still immature. This is because this type of touch interaction device needs finger feeling and surface vibration, therefore, it is necessary to design a reasonable suspension structure for the touch screen to ensure that the online vibration motor drives enough vibration to bring users Comfortable tactile feedback and vibration experience. However, due to the strong dynamic coupling relationship between the linear vibration motor and the touch suspension structure, in practical applications, the equivalent parameters of the linear vibration motor are obtained ba...
