A method for controlling the electrical drive system includes: receiving a machine current signal and a machine voltage signal of a machine current supplied to the electrical machine; determining a switching signal based on the machine current signal and controlling the inverter with the switching signal; estimating a first speed estimate from the machine current signal; estimating a second speed estimate from the machine voltage signal; and comparing the first speed estimate and the second speed estimate with each other, and, when the first speed estimate and the second speed estimate deviate from each other more than a threshold, activating a fault reaction of the electrical drive system, which sets the electrical drive system to a predefined state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electrical drive system with independent diagnostics","description":"An electrical drive system including an inverter and an electrical machine supplied by the inverter.
