Dynamic periodic observer for a combustion engine test bench

In recent years, shortening of the total development cycle for a completed vehicle and reduction of on-board vehicle calibration are increasing in demand in the research and development process in the automotive industry. To meet this demand, the solution is to provide well-suited testbenches. For that, dynamic estimation of the torque produced by the engine is required. The purpose of the paper is to provide a dynamic estimation of the engine torque. Convergence of the observer is proven and experimental results are reported.
