Detection and prevention of non-linear offsets in haptic actuators

A method for determining and mitigating an excessive offset of an internal mass of an electromechanical transducer may include measuring a sense signal associated with the electromechanical transducer in response to a drive signal driven to the electromechanical transducer, determining a non-linear value based on the sense signal, mapping the non-linear value to a probability of the excessive offset of the internal mass, and applying a gain to a signal path configured to generate the drive signal based on the probability. 一种用于确定和减轻机电换能器的内部质量块的过度偏移的方法可以包括测量响应于驱动到机电换能器的驱动信号的与机电换能器相关联的感测信号，基于感测信号确定非线性值，将非线性值映射到内部质量块的过度偏移的概率，以及基于该概率将增益应用于配置为生成驱动信号的信号路径。
