Optimal model‐free control for a generic MIMO nonlinear system with application to autonomous mobile robots

Abstract: In this paper, the design procedure for optimal model-free control algorithm is presented for the tracking problem of completely unknown nonlinear dynamic systems operating under unknown disturbances. The procedure includes a new structure in the context of model-free control and data-driven control algorithms. In the new structure, the unknown nonlinear functions are segmented into 1 unknown linear-in-states part and another unknown nonlinear part. The adaptive laws proposed for estimating the unknown system … Show more

“…Fg=[0;0;gearth] is the vector of gravity force and fq and tq are the vectors of unknown disturbances. The generated force and torques by the electric motors are represented by Fq=[0;0;FT] and τq=[τx;τy;τx] , where their values are completely related with the rotational speeds of the electric motors in the quadrotor . In the following simulation case studies, the values of parameters are M q =2 , J q =1.24 e −3×diag(1,1,2) , K d = K a =0.01 , g =9.81 , fq=1sin(t)v1 , and tq=1sin(t)v3 , where v1=[0;0;1] and v3=[1;1;1].…”
