The present invention relates to a control system of power-assisted artificial limb structure, which comprises a measurement module and an operation control circuit. The measurement module is used to sense a sick leg of a human body to generate at least an electromyographic signal and a sole pressure signal. The operation control circuit is coupled to the measurement module and receives the electromyographic signal and the sole pressure signal to generate a control signal according to a gait mapping table. The control signal is used to control an artificial limb structure for simulating the gait of a human body. As such, the present invention employs the operation control circuit to convert the electromyographic signal and the sole pressure signal into a control signal according to a gait mapping table in order to control an artificial limb for simulating the ankle joint angle of a healthy leg of the human body, so as to achieve the symmetry of ankle joint angles for the sick leg and the healthy leg while the human body is walking and to reduce the consumption of physical power.本發明係有關於一種動力輔助義肢結構之控制系統,其包含一量測模組與一運算控制電路。量測模組係用以感測一人體之一患側腳而產生至少一肌電訊號與至少一腳底壓力訊號,運算控制電路係耦接量測模組,並接收肌電訊號與腳底壓力訊號而依據一步態對應表產生一控制訊號,控制訊號用以控制一義肢結構模擬人體之步伐。如此,本發明藉由運算控制電路依據步態對應表而轉換肌電訊號與腳底壓力訊號為控制訊號,以控制一義肢結構模擬該人體之一健側腳之踝關節角度,而達到該人體行走時健患側腳踝關節角度之對稱性,並減少耗費體力。1‧‧‧控制系統10‧‧‧量測模組12‧‧‧第一患側量測電路120‧‧‧第一患側量測電極122‧‧‧第二患側量測電極124‧‧‧患側量測處理電路14‧‧‧第二患側量測電路140‧‧‧患側腳底量測單元142‧‧‧患側分壓電路20‧‧‧運算控制電路22‧‧‧辨識單元24‧‧‧運算單元26‧‧‧判斷單元30‧‧‧義肢結構50‧‧‧震動元件60‧‧‧刺激單元
