Musculoskeletal disorders caused by heavy workloads are very common in workers, which negatively affects workers' health and productivity. In this regard, the idea of designing an exoskeleton robot is proposed. This robot is similar to a dress which worn on the user's body and parallels the body, accompanying and helping the person. In this paper, the parallel distributed compensation control method is proposed to be applied to a four degrees of freedom exoskeleton waist robot. Initially, the dynamical equations governing the system are extracted. According to the nonlinear nature of the system, the parallel distributed compensator controller is designed with a Takagi-Sugeno linearization approach. The closed loop system response of this controller is investigated in the Simulink environment of the MATLAB software. The results show that the Takagi-Sugeno linearization approach accurately estimates the nonlinear system, and also the proposed controller perfectly intercepts the optimal closed loop response
