1 The results of simulation indicate that the compensating error of time delay is small, and the method can process the target information supplied by TADIL accurately.

2 The compensation system is a practical method for compensating error.

3 The measurement process of the attitude angle based on single trailing earth horizon sensor is investigated, and an analytical formula of attitude compensating error is obtained.

4 A method that measuring angular displacement error, identifying parameters of error model and compensating error automatically was put forward based on inductosyn angular measuring system.

5 This paper describes the effect of harmonic winding and harmonic compensating error on electrical machines in automatic control system.
