Optimum Design of Fractional-order PID Controllerwith a Modified Genetic Algorithm Based on the State-space

Kongzhi Yu Xinxi Jishu, 2019
Fractional-order PID (FOPID) controller has so many parameters that the traditional tuning methods are difficult to achieve. So it presented a modified genetic algorithm based on the state-space (MGABS) to optimize the parameters of the FOPID controller.
