Abstract

Robot is the subject of extensive research by many scientists due to their significance in various fields of life and industry. Precise control of a robot’s motion and position not only enhances work efficiency but also ensures safety, quality, and broadens the potential applications in different domains. This article discusses the development of a model and simulation of the LQR and LQG control algorithms for a 2-degree-of-freedom manipulator using MATLAB/Simulink software. The primary objectives are high accuracy, simple processing techniques, and reduced manufacturing costs for the robot. The LQR algorithm provides effective control near the equilibrium point, while the LQG algorithm optimizes control and noise handling. Simulation results demonstrate that the system operates stably, accurately, and reliably, even in the presence of noise.
