In this paper, a new type of control strategy with fixed-time convergence is proposed for partial integrated guidance and control (IGC) design. First, in order to estimate and compensate for uncertainties in the second order system, a novel fixed-time extend state observer (FxTESO) is designed. Second, a fixed-time sliding mode with a continuous piecewise function is constructed by regulating the index of system states, which can avoid singular problem. Then, this new control strategy based on FxTESO is applied to IGC design, which can achieve fixed-time stability. Finally, the efficiency of the designed strategy is shown by numerical simulations.
