一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID 参数必须由具体对象通过实验确定。由于单片机的处理速度和ram资源的限制，一般不采用浮点数运算， 而将所有参数全部用整数，运算到最后再除以一个2的N次方数据（相当于移位），作类似定点数运算，可 大大提高运算速度，根据控制精度的不同要求，当精度要求很高时，注意保留移位引起的“余数”，做好余 数补偿。这个程序只是一般常用pid算法的基本架构，没有包含输入输出处理部分。 (A typical PID process, using the microcontroller as a control cpu, make some simplification, the specific PID parameters must be determined experimentally by a specific object. As the chip processing speed and ram resource constraints, generally do not use floating-point operations, and all parameters of all integers, and divided by an operator to the last N-th power of 2 data (the equivalent of the shift) for a similar fixed-point operations, can greatly improve the speed of operation, according to the different requirements of precision control, when high precision, attention to retain the shift caused by the " remainder" and on the remainder of compensation. This procedure is commonly used basic structure pid algorithm, does not include input and output processing section.)
