The microcomputer generates a control signal on the basis of duty command values Du, Dv, and Dw to control the drive circuit. The microcomputer includes a dead time compensation section that corrects the duty command values Du, Dv, and Dw on the basis of dead time compensation values Ddu, Ddv, and Ddw. The dead time compensation section includes a basic compensation value computation section that computes a basic compensation value Dd as a fundamental value of the dead time compensation values Ddu, Ddv, and Ddw, and a filter section that performs a filtering process corresponding to a low-pass filter on the basic compensation value Dd. The dead time compensation section sets the dead time compensation values Ddu, Ddv, and Ddw on the basis of an output value α from the filter section."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Motor control device and electric power steering device","description":"A motor control device includes a motor drive circuit and a microcomputer that controls the drive circuit.
