This THESIS deals with the analysis, formulation, design, application and graphical simulation of three sophisticated techniques of nonlinear multivariable dynamic digital control, that allow to realize the spatial trajectory control of the end operation devices of a six angle joints robot, respecting a determined referential framework. The main proposed is to endow it the robot the capacity to operate freely in the cartesian space with all joints simultaneously driven with brushless DC motors. Previously it has been the analyzed, formulated and simulated the Robot Geometry, to position and orient the operational effector, Robot Kinematics, for specifying the spatial movement, the Robot Dynamics for describing the physical behavior, including besides, the motors’ equations, position and speed transducers’ equations, in order to obtain the total dynamic formulation of the actuator-robot-sensor system. In order to achieve, it must be established a “Digital Dynamic Control Law“ to generate voltage variables of motors of each joint and so, to control the robot joint vector to follow a planned trajectory in the joint or cartesian space. These control techniques are: 1) Control by Nonlinear Compensation, it is applied when the system total dynamics is formulated precision and is not affected by disturbances neither uncertainties. 2) Control by Adaptive Compensation, it is applied when the system dynamics is fully specified and the effect of extant structural variations and disturbances can identify and attenuate them by the adaptation of an optimal residual quadratic controller. 3) Optimal Adaptive Self¬tuned Control, it is applied when the system dynamics lacks precision and it is exposed to disturbances or uncertainties and subjected to structural variations, utilizing for that, a dynamic identification method of system parameters and designing an optimal recursive and adaptable control strategy for any spatial trajectory. Therefore to formulate and analyze each control technique it is included the graphical simulation of involved variables in time and space using the MatLab program followed by concluding table-summary showing satisfactory results.
