Abstract For a class of complex industrial process which structure is unclear and the dynamic characteristics changing
strongly with different operating conditions, unmodeled dynamics driven nonlinear PID control method is proposed in this
paper, the algorithm combined the data modelling technologies and control strategy based on process model and is applied
to the Pendubot balance control system. One step ahead of the optimal control strategy is used to design the parameters
of the PID controller, which combined with the nonlinear compensation technology for integrated design. The general
principle and method of choosing PID controller parameters and nonlinear compensator design are given theoretically,
which provides ways and means to solve the problem that the traditional PID controller parameters are difficult to design.
Then, the stability and convergence of the closed-loop system are analyzed. Finally, through the numerical simulation
and the comparative experiment on Pendubot balance control system, the experimental results show that the proposed
algorithm can effectively eliminate the influence of the unknown time-varying uncertainty of the system when the accurate
friction model of Pendubot is unknown, and reduce Pendubot angular fluctuations as far as possible, the swing Angle is
controlled within the specified target value range.
Key words Data driven, increment of unmodeled dynamics, PID, stability, Pendubot
