To solve this problem applied fuzzy-based tuning In this project we have following objectives: To have precision type of controller played an important role. The dynamic parameters of the system are identified by using the logarithmic decrement algorithm, while the control schemes are based on linear quadratic control (LQR) and computed torque control (CTC), respectively. factor ï¿½ï¿½ï¿½ which is a coefficient varies between half to two. Abstract In this paper, a Simulink Robotic Toolkit (SRTK) for the Puma 560 robot manipulator is developed on the MATLAB/SIMULINK-based platform. The The control techniques implemented are the linear quadratic regulator (LQR) [12,13] and the computed torque control (CTC). The proposed ATDC-SM provides a new adaptive law imposing time-varying boundedness that is developed to adjust the control gains appropriately while suppressing the negative impact generated by the robot manipulators. The outputs represent the dynamic estimator to estimate the nonlinear dynamic equivalent in supervisory fuzzy sliding mode algorithm. In order to reduce the chattering this research is used the linear saturation function boundary layer method instead of switching function method in pure sliding mode controller. Verify that the controller in the simulated environment. Also, the RMS errors for tracking a step input of CTC were equal to [2.5E-14, 4.4E-14, 5.0E-14, -4.7E-14, -3.9E-14, -4.6E-14] (deg) and of PD+G were equal to [-1.77E-5, -1.22E-6, -4.28E-6, -8.97E-6, -1.32E-5, 1.05E-5] (deg) for joints one to six, respectively.

Compared with other minimally invasive surgery approaches, robot-assisted surgery gives the surgeon better control over the surgical instruments and a better view of the surgical site. covered negative points. Robotically-assisted surgery was developed to overcome the limitations of minimally-invasive surgery and to enhance the capabilities of surgeons performing open surgery. These synergistic effects provide a fast convergence rate while producing stable control gains. respectively. On the windows machine, run the client "Desktop/cs225a/cs225a.exe". The contribution in this method are, firstly, to reduce the huge number of fuzzy rules required in the normal design for PIDFLC from 512 rules (in the case of three inputs PIDFLC) to 64 rules (in the case of two inputs PIDFLC).
