Extending locked range of digital phase-locked loop by prediction estimation of states

A method to extend locked range of the positive zero crossing detection digital phase-locked loop（ZC-DPLL） was proposed.The nonlinear dynamical model of phase error of a non-controlled DPLL is firstly built,linearation predic-tion estimation of phase error in the stationary point domain is derived.T...
