Claim:
A control System comprising: a plurality of oscillation control devices that generate control signals; and a target signal generating device that generates a target signal for each of the oscillation control devices, the target signal entraining the oscillation control devices to synchronized movement, wherein each of the oscillation control devices is an oscillating system which has a limit cycle and which operates independently of the other oscillation control devices, including: a signal generating unit that generates a control signal based on a parameter concerning an amplitude and a parameter concerning a period of the control signal; and a regulating unit that regulates the parameter concerning the amplitude and/or the parameter concerning the period based on the target signal and the control signal and thereby an amplitude and a period of a control signal generated by the oscillation control device can be independently controlled, assuming that X i is the target signal for the i th (i is a natural number equal to a number of the oscillation control devices or less) oscillation control device, the target signal generating device generates a signal x R obtained by a following equation: ⅆ 2 ⁢ x R ⅆ t 2 - 2 ⁢ ɛ ⁡ ( A 2 - x R 2 ) ⁢ ⅆ x R ⅆ t + B 2 ⁢ x R = 0 , where A is a parameter concerning an amplitude of the target signal, B is a parameter concerning a period of the target signal, and ε is a predetermined constant indicating a nonlinear ratio, and the target signal generating device generates the target signal X i for the i th oscillation control device based on the following equation: X i = c i ⁢ ⁢ 1 ⁢ x R + c i ⁢ ⁢ 2 ⁢ τ ⁢ ⅆ x R ⅆ t , where c i1 and c i2 are constants indicating phase differences of the i th oscillation control device, and constant expressed by the following equation: τ = max ⁡ ( x R ) max ⁡ ( ⅆ x R ⅆ t ) = 2 ⁢ ⁢ A max ⁡ ( ⅆ x R ⅆ t ) , and constants c i1 and c i2 satisfy three conditions, that is ΣC i1 =ΣC i2 as a first condition, C i1 +C iZ =1 or −1 as a second condition, C 21 ≠C 41 and C 11 ≠C 31 as a third condition.
