“…In case the speed difference evaluates a negative value, which means that the evaluated speed is over the threshold, the controller increases the gain of the voltage source to the brake circuit by increasing 𝜏 . Consequently, a control action 𝑢(𝑡) = 𝐾 𝑒(𝑡), proportional to the angular speed error, 𝑒(𝑡), is deployed, where 𝐾 is the proportional gain [19].…”

Physical rehabilitation aims to help people recover their mobility and strength after an injury or illness. One way to evaluate progress in rehabilitation is through isokinetic prototype tests that describe the dynamic characteristics of an isokinetic leg extension device for rehabilitation and control action. These tests use an isokinetic system to assess muscle strength and performance in a patient during isometric or isokinetic contraction. An experimental prototype allows the performance of the device to be evaluated in a controlled environment prior to use by the patient. In order to achieve physical recovery from musculoskeletal injuries in the lower limbs and achieve the reintegration of the affected subject into society as an independent and autonomous individual in their daily activities, a control model is presented that introduces a medical isokinetic rehabilitation protocol, where the element that allows carrying out such protocol consists of a magnetic particle brake whose control action is strongly influenced by the dynamics of the system when in contact with the end user, specifically the patient's legs in the stretch from the knee to the ankle. The results of these tests are valuable for health professionals seeking to measure their patient’s progress during the rehabilitation process and determine when it is safe and appropriate to advance in their treatment.

“…More recently, [9] designed self-tunnig fuzzy sliding mode control using the decoupled method. In addition [10] developed the model by applying the Euler-Lagrange equations, and the design of sliding model control is presented. In, [11], a full constructive procedure is presented, which obvious the necessity of solving PDE to shape the energy for a class of mechanical systems.…”
