Abstract: Closed Loop Control Systems are often used to control movement of patient paraplegic’s lower limbs. Using a neurostimulator applied to the quadriceps muscle, which causes muscle contraction and causes the movement of the joint knee, one has the feedback signal related to the joint knee angle, which can be obtained using an electrogoniometer. In this text, a Proportional-Integrative-Derivative-Accelerative (PIDA) controller is designed, in order to vary the joint knee angle of patients paraplegics until 45º, by Functional Electrostimulation. By specification of project, it is known that the poles of the system can vary into the complex plan, so, classic methods of control, like Analysis of Performance Indexes, Routh-Hurwitz Stability Criterion, PI/PD/PID/PIDA controller, are used to develop a controller that meets the requirements. The procedure of search will be realized by simulations on MATLAB®, which has the necessary packages math tools for experimental simulation of the concepts used in this research.
