TL;DR: In this article, an extension of the Action Governor (AG) supervisory scheme to a nominal control loop to enforce safety-related requirements is presented, which enables AG design based on discrete-time piecewise affine (PWA) system models with additive set-bounded disturbance inputs and nonconvex exclusion-zone avoidance constraints.
Abstract: In this letter, we introduce an extension of the Action Governor (AG), which is an add-on, supervisory scheme to a nominal control loop to enforce safety-related requirements. This extension enables AG design based on discrete-time piecewise affine (PWA) system models with additive set-bounded disturbance inputs and non-convex exclusion-zone avoidance constraints. We establish theoretical properties and computational approaches for this robust version of AG, and illustrate its application to an autonomous vehicle control problem.

TL;DR: The presented analysis shows that the off-going clutch can reduce either shift time or RMS jerk index by introducing power recirculation via the two clutches, which is in turn paid for by certain increase of AT energy loss.
Abstract:
The paper presents a detailed numerical and algebraic analysis of potential for improving the step ratio automatic transmission (AT) upshift performance by means of modulating the off-going clutch during the inertia phase. The numerical analysis is based on Pareto optimal frontiers obtained by using the previously developed methods for AT shift control trajectory optimization and piecewise-linear control profile parameter optimization, where the control objectives include minimization of shift time, vehicle RMS jerk, and clutch dissipated energy. The analysis concerns the following control scenarios related to inertia phase: 1) oncoming clutch control only, 2) combined action of oncoming and off-going clutch; 3) oncoming clutch control extended with engine torque reduction control, and 4) combining all three control actions. The numerical results relate to an advanced 10-speed AT and various single-step and double-step upshifts, with emphasis on 1-3 shift. The numerical analysis results are proven algebraically based on a simplified AT model represented in bond graph form. The presented analysis shows that the off-going clutch can reduce either shift time or RMS jerk index by introducing power recirculation via the two clutches, which is in turn paid for by certain increase of AT energy loss.

TL;DR: In this paper, an elongated hexagon was designed based on the design of the frog toe and other natural hexagonal surfaces such as snakes, where the crossing grooves are oriented nearly perpendicular to the sliding direction.
Abstract:
We thank the discussant for their interest in our manuscript and their very helpful remarks. Existing tribological studies of biomimetic surfaces were mostly focused on dry friction and biological surfaces are highly deformable. Therefore, the learnings on the effects of textures may not be directly translate to fully lubricated interfaces. Nonetheless, we agree that we can still learn much from these studies. Investigating additional orientations of the elongated hexagon could possibly improve the frictional response of the lubricated surfaces. Given that existing literature indicates that orienting the hexagons with two edges perpendicular to the sliding direction yields lower friction than in the case of edges parallel to the sliding direction [1], the experimental conditions in the manuscript could be the worst-case scenario and thus a lower bound for frictional improvement. Additionally, the hexagon was designed based not only on the design of the frog toe (and other natural hexagonal surfaces such as snakes) but also on existing industrial piston cylinder liner designs, where the crossing grooves are oriented nearly perpendicular to the sliding direction [2, 3]. Hence, our tested design is an extension of that existing technology with learning from nature. However, the suggestions to expand the experiment with additional hexagonal orientations is well received and will be considered for future work.
