This paper presents a lead phase iterative learning control (ILC) scheme along time axis using two-band filter with time window to restrain periodic force ripples of permanent magnet linear synchronous motor (PMLSM). The purpose of introducing low-pass filter is to made accumulation of random noises to be decreased along the iteration axis, and to utilize the enhanced robustness given by two low bandwidth...
The intelligent press forming of sheet metal is a completely new and comprehensive technology that combines control-science, computer science, material science and metal forming theory. Although the technology originated in 1980s from America, it had focused on the spring-back of V-shaped bending. The author expanded the the research field to the axis-symmetric part and non-axis symmetric part and...
A new repetitive adaptive compensation scheme is proposed for the dynamic friction and periodic ripple moment in a DC motor system. The paper's contribution is to add repetitive control scheme into the adaptive-based compensation scheme. A LuGre dynamic friction model with non-uniformly variational parameters is used in the motor system. The compensation algorithm consists of a PD component, an adaptive...
