On angular stabilization of vehicle with the aid of nonlinear control

The problem of improving of vehicle angular stability by introducing into control law nonlinear (cube) terms of variable parameters is considered. The problem relates to the class of problems on analytical design of controllers [1]. Introduction of nonlinearities in such a statement was suggested by E. P. Popov [2], studies of some interesting cases were conducted in [3], literature survey on this problem is given in [4]. Studies of cube terms effect was carried out by the multi-term transform method, and conclusions on the choice of nonlinear control law were made.
