The presence of low-frequency oscillation modes with low-damping rates can compromise the operating performance of power systems. The development of synchronized phasor measurement systems allowed the development of damping controllers based on Phasor Measurement Unit (PMU) data and the results are promising in improving the damping rates of oscillation modes. However, this controller relies on reliable data from PMUs that may be subject to failure from cyber-attacks. This paper proposes a controller design method using the Reptile Search Algorithm (RSA) algorithm considering robustness to multiple loss of information in the communication channels in the design stage. Case studies were conducted on IEEE 39-bus system and the results showed that the proposed method is effective for improving system damping when subjected to PMU data losses. However, these data losses can not be in large amounts, the greater the combination of data losses, the greater the control design difficulty.
