In this letter; we design a model predictive controller (MPC) for systems to satisfy Signal Temporal Logic (STL) specifications when the system dynamics are partially unknown; and only a nominal model and past runtime data are available. Our approach uses Gaussian process regression to learn a stochastic; data-driven model of the unknown dynamics; and manages uncertainty in the STL specification resulting from the stochastic model using Probabilistic Signal Temporal Logic (PrSTL). The learned model and PrSTL specification are then used to formulate a chance-constrained MPC. For systems with high control rates; we discuss a modification for improving the solution speed of the control optimization. In simulation case studies; our controller increases the frequency of satisfying the STL specification compared to controllers that use only the nominal dynamics model. © 2017 IEEE;
