LASER SENSOR, CONTROL METHOD OF LASER SENSOR, AND RECORDING MEDIUM STORING CONTROL PROGRAM OF LASER SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18158815 titled 'LASER SENSOR, CONTROL METHOD OF LASER SENSOR, AND RECORDING MEDIUM STORING CONTROL PROGRAM OF LASER SENSOR
Simplified Explanation
The patent application describes a laser sensor that uses a mirror to scan laser light at different angles.
- The sensor includes a driving waveform generation circuit that generates a driving signal to control the mirror's amplitude.
- The amplitude of the mirror is controlled based on an amplitude command value, which is determined by a target amplitude that defines the scanning range of the mirror.
- The sensor also includes a feedforward circuit that reflects a transient model, which accounts for temporary changes in the mirror's amplitude over time due to the driving signal.
- The feedforward control is used when the target amplitude is changed, and it uses a target model to predict the temporal change of the mirror's amplitude based on the amplitude command value.
Original Abstract Submitted
A laser sensor includes: a mirror configured to scan a reflection angle of laser light; a driving waveform generation circuit configured to generate a waveform of a driving signal that controls an amplitude of the mirror, according to an amplitude command value based on a target amplitude that defines a scanning range of the mirror; and a feedforward circuit configured to reflect a transient model in a case where the amplitude of the mirror transiently changes with time according to the driving signal in a case where the target amplitude is changed and a target model of a temporal change of the amplitude of the mirror on the amplitude command value through feedforward control.
