摘要
针对原有校音器驱动器控制系统输出响应曲线波动幅度过大,导致其驱动器损伤较大的问题,提出基于单片机技术的高性能校音器驱动器自动控制系统设计。采集声音信号,经过二次转化,得到数字信号,利用单片机技术,去除噪声干扰,防止系统异常;将输入量模糊化处理,完成数值转换,采用PID控制算法,得到在离散状态控制规律,结合实际情况,调整控制系数,完成自动控制系统的设计。根据模拟实验,验证所设计系统的有效性,实验结果表明,与原有系统相比,所设计控制体统的输出响应曲线波动幅度明显减小,改善了原有系统的缺陷,其控制更加稳定。由此可见,该设计有效。
Aiming at the problem that the output response curve of the original controller driver control system fluctuates too much,which leads to great damage to the controller,an automatic control system design of the controller driver with high performance based on microcontroller technology is proposed.Collecting the sound signal,through secondary conversion,the digital signal is got,the microcontroller technology is used remove the noise interference,are prevent the system abnormal.The input amount is fuzzified,the numerical conversion is completed,the PID control algorithm is adopted,the control law in the discrete state is obtained,combined with the actual situation,the control coefficient is adjusted,and the design of the automatic control system is completed.According to the simulation experiment,the validity of the designed system is verified.The experimental results show that compared with the original system,the fluctuation amplitude of the output response curve of the designed control system is obviously reduced,which improves the defects of the original system and makes the control more stable.Thus,the design is effective.
