In the space of the system parameters, the stability charts are determined for the delayed and damped Mathieu equation defined as ẍ (t) + KẊ (t) + (δ + ε cost) × (t) = bx (t - 2π). This stability chart makes the connection between the Strutt-Ince chart of the damped Mathieu equation and the Hsu-Bhatt-Vyshnegradskii chart of the autonomous second order delay-differential equation. The combined charts describe the intriguing stability properties of an important class of delayed oscillatory systems subjected to parametric excitation.
