Abstract | The auto-disturbance rejection control approach is used in this paper to solve the trajectory tracking control problem of three-joint mechanical manipulators. The three-joint manipulators is a system with nonlinear, uncertainty, strong coupling, and is a multivariable system that is closely related to the principle of kinematics and dynamics. In the adopted auto-disturbance rejection control technology. The tracking differentiator is able to solve the problem that the system output cannot track the jumping reference well due to system inertia. The nonlinear state error feedback control law improves the traditional PID control with linear combination of tracking errors. The extended state observer estimates in real-time and compensate the sum of inside and outside disturbance, and eliminates the influence of internal and external interference on the system. By using the decoupling control method in the auto-disturbance rejection control technique, three joint mechanical manipulator controller's design is finally realized. Finally, an illustrative example is presented to show the effectiveness and superiority of the auto-disturbance control method. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
