Abstract : "We present a hybrid-type observer for detecting the switching time and estimating both the active mode
and the states of continuous-time switched linear systems. The systems under consideration have external inputs
and are affected by unknown disturbances. In addition, noise corrupts the output measurements. In this setting
the switching cannot be detected immediately, and thus, this paper presents a condition that relates the amount of
delay to the sizes of the unknown disturbances/noises, the external inputs, and the states, and the strength of the
observability. Once the condition is satisfied, the proposed observer and algorithm return the exact active mode
and approximate state information of the switched system. A numerical example is also presented to show the
performance of our algorithm.."
