【Abstract】 A two dimensional discrete system with chaotic and hyperchaotic characteristics and the control of chaos and hyperchaos by means of time delayed variable feedback have been realized in an electronic circuit.Both the complex behaviours in the circuit without control and the various stabilized periodic states in the controlled circuit are in good agreement with the results obtained by analyzing theoretically and simulating numerically.In addition,the experimental results confirm that it is effective to control chaos and hyperchaos by using the method of improved time delayed variable feedback.更多还原
