A Design Method of Temperature Controller for High-Precision Laser

The temperature stability of the high-precision laser is conducive to the stability of the laser's electronic parameters, improves the output energy of the optical signal, and improves the measurement accuracy. In the past temperature control systems, many controllers have been proposed to ensure their accuracy performance, including positional control and classic PID control. But in the harsh application environment, the classic controller can not meet the requirements, so this paper proposes a new PID control method-parameter optimization fuzzy self-tuning PID (POFPID), based on the analysis of the instrument heating model, based on actual test data. System model fitting. Combining the fitting model and fuzzy theory improves the simulation for PID, and obtain the appropriate parameter range in advance. Therefore, the debugging time can be greatly saved in the actual debugging, and at the same time, due to the reasonable parameter range, the heating and cooling are prevented from being out of control, and the high-precision optical instrument can be well protected. The final result shows that the temperature control system designed in this paper can track and control the temperature of the instrument well. And because the function is first fitted and simulated, and then the actual debugging is carried out with the help of the obtained parameters, the debugging progress is greatly accelerated, and the loss of the high-precision instrument reaches a small level.
