Turning point based fatigue testing: Combining multisines with turning point replication

An alternative update formula for non-linear model-based iterative learning control

“…18) is also the form of the ILC algorithm in response reconstruction for purposes of automotive fatigue testing. For implementations with a linear inverse inL see [21], [24], [25], [26], [27], and [28]. For an implementation with a nonlinear inverse inL see [7].…”

A Theoretic Analysis Method Research of Load Appling Based on Response Control in Time Domain

“…Sometimes the time domain response is adopted as the target response, especially in fatigue testing of vehicle and earthquake wave analysis [1] , in fact it belongs to the field of time wave replication (TWR) which used widely in impact test. Many researchers have studied TWR, lots of their works focused on the design of control system, such as Yan [2] , a multi-dimension waveform replication control system is developmented. Recently work by Deckers [3] proposed an idea of replicating the turning point, it needn`t to be exactly equal for all time samples, the controlled signal should have the same turning points as the target signal.…”
