Ball screw feed-drive system (BSFDS) is a widely used high-precision positioning mechanism, and its accuracy strongly limited by friction, vibration, etc. Those factors are difficult to model or completely. Since the data-driven control approach not dependent, it suitable overcome previous problems. Iterative learning (ILC) one of general unfixed-structure approaches, but restricted residual error. Therefore, this article proposes combined fixed-structure feedforward method. Notably, part...
Abstract Small-angle measurement tools with pendulum mechanical structure face two major challenges. One is that it takes a long time to wait for the completely stop swinging, and other instrument has poor anti-interference ability. Inspired by challenges, in this paper we propose dynamical method achieve fast accurate synchronously. Specifically, damped oscillation modeling of nonlinear least-squares fitting presented estimate model parameters, which includes angle oblique plane. In...
