Description: （1）位置式PID控制的输出与整个过去的状态有关，用到了误差的累加值；而增量式PID的输出只与当前拍和前两拍的误差有关，因此位置式PID控制的累积误差相对更大；
（2）增量式PID控制输出的是控制量增量，并无积分作用，因此该方法适用于执行机构带积分部件的对象，如步进电机等，而位置式PID适用于执行机构不带积分部件的对象，如电液伺服阀。
（3）由于增量式PID输出的是控制量增量，如果计算机出现故障，误动作影响较小，而执行机构本身有记忆功能，可仍保持原位，不会严重影响系统的工作，而位置式的输出直接对应对象的输出，因此对系统影响较大。-(1) Position PID control output and the entire state of the past, used the accumulated value of the error incremental PID output only error with the current beat and shot the first two, and therefore the position of the cumulative error PID control relatively greater (2) incremental PID control is to control the amount of incremental output, there is no integral action, so this method is suitable for the implementation of the object body with integral components, such as stepper motors, etc., and positional PID applicable Object actuators without integral components, such as electro-hydraulic servo valve. (3) Since the incremental PID control output increment, if the computer failure, malfunction less affected, while executing agency itself has memory function, can remain in place, will not seriously affect the operation of the system, and positional output directly corresponds to the output object, so a greater impact on the system.

Description: 死区效应的存在使得逆变器输出电压和电流不能跟踪参考电压和电流，同时输出增加了谐波分量，使系统的输出转矩存在很大脉动，尤其电机在低速运行时，可能导致系统的不稳定。针对此问题分析了死区效应对于交流伺服系统的影响，特别是低速运行时对电流波形的影响。提出了一种新型的在线延时补偿算法，该算法可以省掉开关器件没有必要的开通和关断，且不需要任何额外的硬件电路和离线的实验测量，具有实现简单、输出波形谐波含量小等特点，较好地降低了系统在低频时输出电流的脉动。仿真与实验表明该算法有效、可行。-The existence of invener dead time makes the output voltage and current of inverter be different its rcference voltage and current．Dead time of inVerter increaSes me harmonic of invener output锄d makes the output torque

innuence of inverter dead time on AC servo system， especially in the condition of low speed，was analyzed．Aw
on—line dead time delay compensation algorithm was proposed to impmVe tlle inVener output performance．The
triggers fbr the invener switches，additional circuits or off-line experimental measurement are unnecessary． The rcalization of the algo^thm is simple and the hanIlonics in

Description: 舵机及电机PID控制算法： 谈谈PID各自对差值调节对系统的影响：
1、单独的P（比例）就是将差值进行成比例的运算，它的显著特点就是有差调节，有差的意义就是调节过程结束后，被调量不可能与设定值准确相等，它们之间一定有残差，残差具体值您可以通过比例关系计算出。。。增加比例将会有效减小残差并增加系统响应，但容易导致系统激烈震荡甚至不稳定。。。
2、单独的I（积分）就是使调节器的输出信号的变化速度与差值信号成正比，大家不难理解，如果差值大，则积分环节的变化速度大，这个环节的正比常数的比例倒数我们在伺服系统里通常叫它为积分时间常数，积分时间常数越小意味着系统的变化速度越快，所以同样如果增大积分速度（也就是减小积分时间常数）将会降低控制系统的稳定程度，直到最后出现发散的震荡过程，。。。这个环节最大的好处就是被调量最后是没有残差的。。。
3、PI（比例积分）就是综合P和I的优点，利用P调节快速抵消干扰的影响，同时利用I调节消除残差。。。(PID control algorithm for rudder and motor)
