This paper studies the distributed singularity dispelled fixed-time quantized consensus tracking control for quite a large family of power-chained (powers are positive odd integers) nonlinear multi-agent systems in the presence of uncertainties. It is extremely challenging to achieve fixed-time consensus for such dynamics because conventional feedback linearization and backstepping method successfully developed for low-power systems fail to work, and some exponential terms typically arising from fixed-time stability are difficult to design due to the existence of high powers and strong couplings among distinct agents. The fixed-time consensus tracking is realized by incorporating adding-one-power-integrator methodology into our newly proposed more general fixed-time stability criterion which is available for approximation based dynamics. The singularity issue existing ubiquitously in fixed-time control is overcome by delicately introducing a switching singularity dispelled function. Moreover, a variable-separable lemma is utilized to extract the input quantization in a “linear-like” manner and fuzzy approximators are utilized to estimate the uncertainties in system. It is rigorously proved that the consensus tracking error eventually converges to a residual set in fixed time, while the boundedness of all closed-loop signals are guaranteed. Numerical and practical simulations further verify the effectiveness of proposed scheme.
