【Abstract】 The single chip computer controlling arc-spraying system is studiced and its model is established. This provides a theoretical basis for optimal control. Arc voltage and current feedback controllers are also developed. A PC used for sampling spraying process parameters communicates with single chip computers in series and obtains on-line modifying PID controller’s parameters. Using genetic algorithm to optimize PID controller’s parameters has realized the adaptive arc-spraying process control and achieved satisfactory spraying results.更多还原
