Design of Multi-variable PID Controller based on SFSO Algorithm

To solve the parameter tuning problem of the multi-variable PID controller of the distillation tower,a new intelligent optimization algorithm,SFSO was applied to the design of multi-variable PID controller.The global optimal solution of PID controller parameters is determined using off-line method.The simulation result shows that system has a good anti-jamming performance,less overshoot,short setting time in system step response.
