Abstract: The poor uniformity is the key problem to keep IC oven high efficiency.An optimal genetic control algorithm is used in new advanced IC oven,which is not sensitive to oven's initial condition,could find globally optimal solution,and has strong adaptability.The result of experiment data indicates that the new method could improve speed regulation of temperature,reduce settling time and overshoot,and the new control algorithm has better interference suppression and robustnessthan regular algorithm.
