【Abstract】 This paper presents a method for predication, estimation and control of the state of power unit in power and electric equipment. Which use the method, the unit can always run in the safely temperature area, and then the malfunction can be avoided through the method of parameter control, so the running quality of the driving system can be guarantied, and the damage to the power unit can be prevented, and the optimized control level of the system would be improved.更多还原
