由于伺服系统中积分器产生的斜坡信号难以处理，至今还没有一种有效的控制器设计方法来实现对传感器故障的容错。在本文中，我们得到了一个关键的限制功能的有限积分器，以有效地表现为措施，对斜坡信号的第一次。然后，限制功能和控制器可以设计在一个统一的框架，同时优化考虑在正常情况下，在故障情况下的伺服性能。所得到的结果成功地建立了潜在的适用性有限积分器的容错伺服系统。
No effective controller design for achieving the tolerance against sensor failures has been proposed for servo systems until now because it is difficult to deal with ramp signals generated by integrators in the servo performance. In this paper, we obtain a key for the limiting function in limited integrators to behave effectively as the measure against ramp signals for the first time. Then, the limiting function and a controller can be designed in a unified framework of simultaneous optimization with consideration given to the servo performance in the normal case and in faulty cases. The obtained result succeeds in establishing the potential applicability of limited integrators to fault-tolerant servo systems.
