Abstract :
This paper presents a PID control of a prototype transmission-based robot servo-actuator system (TBA) and its implementation using real time application interface (RTAI) under Linux. The PID control presented can achieve stability and performance requirement in terms of attenuation of disturbance due to gear shift. The control software has a real time multithread design. Verification test shows the new control software has a deterministic control loop time, and significant performance improvement is achieved compared with the implementation using Labview Express under Windows XP
