The graph below is showing the time based behavior of the position reference and the actual position of the motion control system when the system is being operated under the constant speed control by a software based position feedback control scheme with the following 6. conditions The total distance to move: 500 mm Constant moving speed targeted: 10 mm/sed Sampling time of software based digital position servo control: 10 mili-seconds. a) What kind of control algorithm is used in the control system? Why should the control algorithm be used? b) c) How do you implement the motion controller with a microprocessor? d) Obtain the value of DXri (um). e) Explain your idea on reducing the difference between the position reference and the actual position during the motion?

    MATLAB EXERCISE 5 This exercise focuses on the Jacobian matrix and determinant, simulated resolved-rate control, and inverse statics for the planar 3-DOF, 3R robot. (See Figures 3.6 and 3.7; the DH parameters are given in Figure 3.8.) The resolved-rate control method [9] is based on the manipulator velocity equation x = kve, where ky is the Jacobian matrix, is the vector of relative joint rates, X is the vector of commanded Cartesian velocities (both translational and rotational), and k is...
