Angle estimation problem of micro-core sliding film observer SMO [Copy link]

When using the micro-core sliding film observer, it is found that when the compensation is 90 degrees, the observed angle is ahead of the actual angle, and the bus voltage is different, the leading angle is different, the motor is a salient pole motor, and the SMO observer is a surface-mounted mathematical model. I don’t know if it will have any impact. I hope that the experts who understand it can give me some advice. Thank you!!!

By measuring the input and output of the actual system, we can get an estimate of the internal state of a given system.
