The　control　parameter　of　shaking　table　is　one　of　the　key　elements　which　significant　influence　on　the　system　control　performance.　An　algorithm　which　uses　the　model　of　system　identification　to　theoretically　calculate　the　control　parameter　is　put　forward,　and　then　obtains　the　optimal　three-parametric　control　parameter　based　on　theoretical　calculation.　Tuning　algorithm　can　get　more　ideal　control　parameter　and　could　be　applied　in　shaking　table　TVC　parameter　self-tuning.
