A Predictive Safety Filter for Learning-Based Racing Control

چکیده
The growing need for high-performance controllers in safety-critical applications like autonomous driving motivated the development of formal safety verification techniques. In this letter, we design and implement a predictive filter that is able to maintain vehicle with respect track boundaries when paired alongside any potentially unsafe control signal, such as those found learning-based methods. A model (MPC) framework used create minimally invasive algorithm certifies whether desired input safe can be applied vehicle, or provides an alternate keep bounds. To end, provide principled procedure compute invariant set nonlinear dynamic bicycle models using efficient convex approximation fully support aggressive racing performance without conservative interventions, extended real-time through backup trajectories. Applications assisted manual deep imitation learning on miniature remote-controlled demonstrate filter's ability ensure during maneuvers.

Linear model predictive safety certification for learning-based control
While it has been repeatedly shown that learningbased controllers can provide superior performance, they often lack of safety guarantees. This paper aims at addressing this problem by introducing a model predictive safety certification (MPSC) scheme for polytopic linear systems with additive disturbances. The scheme verifies safety of a proposed learningbased input and modifies it as little as ...
متن کاملFinite Control Set Model Predictive Control for a Three-Phase Shunt Active Power Filter with a Kalman Filter-Based Estimation
In this paper, the finite control set model predictive control is combined with the vector operation technique to be applied in the control of a three-phase active power filter. Typically, in the finite control set technique applied to three-phase power converters, eight different vectors are considered in order to obtain the optimum control signal by minimizing a cost function. On the other ha...
متن کاملUnscented Kalman Filter in Adaptive Neural Model-based Predictive Control
An adaptive model-based predictive control scheme is proposed for non-linear systems. This methodology exploits the non-linear modelling capabilities of nonlinear state-space neural networks and the online weights adjustment by means of an unscented Kalman filter. Results from experiments show evidences on its good tracking performance even when the system’s dynamics change.
متن کاملLearning-based model predictive control for Markov decision processes
We propose the use of Model Predictive Control (MPC) for controlling systems described by Markov decision processes. First, we consider a straightforward MPC algorithm for Markov decision processes. Then, we propose value functions, a means to deal with issues arising in conventional MPC, e.g., computational requirements and sub-optimality of actions. We use reinforcement learning to let an MPC...

Indirect iterative learning control (ILC) facilitates the application of learning-type control strategies to the repetitive/batch/periodic processes with local feedback control already. Based on the two-dimensional generalized predictive control (2D-GPC) algorithm, a new design method is proposed in this paper for an indirect ILC system which consists of a model predictive control (MPC) in the ...
