As concerning conventional meter,we 11 be analysing the questions about flow compensation, and making an inquiry into variour factor about influencing flow of form of throttle we ll design the best Compensation plan--complete parameter compensation.

Measurement of resistance by complete compensation method and the analysis of error;

With respect to the compensation for the nonlinear gain within the process control system, a complete compensation principle was proposed according to the inverse functions, and two distinct types of compensation characteristic were deduced.

Selecting suitable generalized output polynomial and using REM algorithm, the controller can provide no tracking error to the varying given input and complete compensation to the observed disturbance.

This paper analyzes mathematical model of temperature and prdssure compensation in measure of stream current amount and puts forward a new thinking way lf computerized omni parameter compensation.

It deduces the voltage compensation method,calculates the asynchronous torque and average torque during the variable frequency starting process,and verifies the validity of the method.

The voltage compensation method was deduced to ensure a constant maximum asynchronous torque during the variable frequency starting process,and the validity of the proposed method by the quasi-steady state method was verified to compute the asynchronous torque and the magnet braking torque of the SPPM employing the voltage compensation method during the variable frequency starting process.
