摘　　要：根据历史数据和专家经验设计了燃气机转速专家PID控制器,对燃气机突加负载转速控制、燃气机变转速控制和抗干扰性能进行实验研究。结果表明:突加负载后燃气机没有出现转速降低或熄火现象,而是达到新的稳定工况且时间小于10 s;变转速调节过程中转速没有出现超调,燃气机达到新的稳定工况,时间小于20 s,专家PID控制器表现出良好的动态响应特性;对于过热度变化引起的燃气机转速波动,专家PID控制器表现出较好的抗干扰性能。According to the historic data and experience from experts,designed was a rotating speed controller for gas engines based on the expert PID control method and experimentally studied were the rotating speed control of a gas engine when it was suddenly added with a load,variable speed control and anti-interference performance of the gas engine.It has been found that no rotating speed reduction and flame failure occurs to the gas engine when it is suddenly added with a load and the time required for attaining a new steady operating condition is less than 10 seconds. No overshoots of the rotating speed emerge during the variable speed control process and the time required for attaining a new steady operating condition is less than 20 seconds. The expert PID controller exhibits its good dynamic response characteristics and for the fluctuation arisen from changes of the superheating degree of the gas engine,the expert controller also displays its relatively good anti-interference performance.
