Nowadays, along with the dramatic development of industrial automatic, optimization problem has been playing an important role in designing controllers for nonlinear systems. This paper proposes a hybrid control design of Fast Output Sampling Discrete Sliding Mode Control (FOSDSMC) and fractional order PID controller (FOPID) based on fireworks algorithm (FWA) to optimize controller parameters. The hybrid controller is verified on a nonlinear inverted pendulum system. The simulation of controller optimization process is carried out using MATLAB/Simulink. The results are compared with two published controllers such as a hybrid control design of PID controller and fast output sampling discrete sliding mode control, and a hybrid control configuration of PID and state feedback controller based on linear quadratic regulator method. The comparison results show the better performance of the proposed method.
