However, vibrations during high-speed motion can significantly affect positioning accuracy and system stability. Traditional PID controllers struggle with nonlinear systems like robotic systems which can lead to significant steady-state errors. This study proposes a new control strategy combining a sliding mode control (SMC) along with a PID control (SMC+PID) to create a new hybrid control approach. Numerical analysis shows that a SMC+PID hybrid control strategy can reduce Z-axis steady-state errors from 0.9848 to 0.1183 and can shorten the time to steady-state by 65 %. Our new hybrid control method has shown to be effective in improving stability and enhancing control accuracy.attitude controlDenavit-Hartenbergmulti-axis robotic armPID controlsliding mode controlsteady-state errorPrecision control of a multi-axis robotic arm using sliding mode control with PID control methodconference paper10.1117/12.3051428
