Stabilization of time-delayed oscillators via digital PD controller is analyzed. The system under analysis is described by the delay-differential equation ẍ(t) + a 1ẋ (t) + a 0x(t) = b 0x(t - τ) - P x(t j-1) - Dẋ (t j-1), t ∈ [t j, t j+1), (1) where t j = jΔt with Δt being a sampling period for the digital controller. The point-delay term x(t-τ) is assumed to be inherently present in the governing equation of the uncontrolled system, while the term x(t j-1) is present due to the digital controller. Since the term x(t j-1) can be represented as a term with a piecewise linearly varying time delay, the system is time-periodic at period Δt. The stability analysis for the system is performed using the semi-discretization method. Case studies are presented for the stabilization of the turning process via digital PD controller.
