In recent years, balance control two-wheeled bicycle has received more attention of scientists. One difficulty of this problem is the control object is unstable and constantly impacted by noise. To solve this problem, the authors often use robust control algorithms. However, robust controller of self-balancing two-wheeled bicycle are often complex and higher order so affect to quality during real controlling. The article introduces the application model order reduction algorithms to reduce order higher order robust controller in control balancing two-wheeled bicycle problem. The simulation results show the correctness of the algorithm is introduced and gives the possibility to practical applications.
