Abstract

AbstractIn this paper, two different quantization control laws are proposed for the single‐link manipulator system with horizontal motion and input signal quantization. Considering the characteristics of distributed parameters of the flexible system, the dynamic model of the system is represented by partial differential equations (PDEs) and boundary conditions. One of the control laws is proposed to follow the desired time‐varying joint angle and eliminate boundary deformation of the link simultaneously. The other control law is proposed to track the required constant angle and suppress the distributed deformation of the link. The two control schemes can not only guarantee the stability of the system but also meet the control requirements under the premise of input signal quantization. Numerical simulations are provided to verify the performance of the controller.
