- Description
- This paper proposes nonlinear control strategies for the discrete-time near time-optimal control of damped servomechanisms. Both the well established Proximate Time Optimal Servomechanism (PTOS) and its dynamically damped version (ddPTOS) are extended for damped systems. Stability results are presented in a general discrete-time framework suitable for both damped and undamped systems. These results allow the reduction of constraints in the traditional PTOS – particularly regarding the acceleration discount factor – while encompassing the nonlinear damping of the ddPTOS. Experimental results demonstrate the efficiency of the proposed controllers.
