The invention provides a hybrid power bionic robotic fish and a control method thereof, and relates to the technical field of bionic robots. The two pectoral fins comprise pectoral fin motors and pectoral fin plates, the pectoral fin plates comprise a plurality of rigid plates, flexible plates and a plurality of limiting mechanisms, the flexible plates are connected with the rigid plates respectively, and each limiting mechanism is arranged between every two adjacent rigid plates, so that the pectoral fin plates cannot be bent when swinging backwards and can be bent when swinging forwards; the tail fin is driven by the tail fin motor to rotate; the controller controls the two pectoral fin motors and the tail fin motor to rotate through a CPG control network, the CPG control network is composed of three oscillator units, and output angles of the three oscillator units correspond to rotation angle changes of the two pectoral fin motors and the tail fin motor respectively. The method has the beneficial effects that the CPG control network is used for controlling coupling cooperative movement of the two pectoral fins and the tail fin, random switching between pectoral fin propelling and tail fin propelling can be achieved, and hybrid driving of pectoral fin propelling and tail fin propelling can be achieved.
