Abstract: Two
new fuzzy controllers are designed，one’s
control rules are adjusted by error integral，another
are with feedforward of error integral. If only the control
rules and parameters are selected felicitously,the
static errors of the system will be eliminated. The test results
show that the controllers can assuredly improve static
performances of the controlled system.
