The Application of Optimal Control in the Constant-Speed Control of Rotary Screen Rack
Aiming to the defects in the traditional speed-control of rotary screen rack,such as poor dynamic performance,poor noise immunity,untimely regulation and strong dependence on personnel and experience and so on,this paper proposes a linear quadratic regulator with status feedback,which was used in the constant-speed control of LHG type rotary screen rack.It can be easily and quickly solve riccati equation by using Matlab software to get the optimal state feedback gain matrix.The simulation result shows that the proposed method is obviously superior to the unit negative feedback control method in dynamic performance,noise immunity and steady precision.
