Presents a simple method of compensating friction against the character of the nonlinear model of a brushless dc motor system which transfers the original system model to a simple linear model using the method of input - output linearization, and estimates the coulomb friction in the system in real - time using a nonlinear friction estimator, and then compensate the friction in the system using a friction feedforward, and concludes from simulation results that this method can effectively eliminate the influence of friction in brushless dc motor systems
針對無刷直流電動機系統的非線性數學模型特點，提出了一種簡單的摩擦補償方法.該方法首先利用輸入輸出線性化方法將原系統模型轉化為一種簡單的線性模型，然後給出一種非線性摩擦估計器實時估計系統中的庫侖摩擦值，最後利用摩擦前饋補償方法對其進行補償.模擬結果表明該方法可以有效地抑制無刷直流電動機系統中的摩擦影響 -
