摘要： Multipliers 21a and 21b output values, which are obtained by multiplying a total drive command value Es by first and second gains G1 and G2, respectively, as first and second drive command values E1 and E2. Controllers 23a and 23b control first and second actuators (motors) 5 and 7, respectively, on the basis of the first and second drive command values. The detection values of the drive amounts of the actuators are denoted by Ef1 and Ef2, respectively, and the detection value of the drive amount of a driven body is denoted by Ef. A gain calculator 27 calculates the gains G1 and G2 on the basis of Ef1, Ef and Ef2. An upper limit value of Ef, which denotes the drive amount of the driven body, is denoted by Lmax. When Ef1, Ef2 or Ef approaches zero, the first gain G1 is brought close to (Ef1−Lmax/2)/(Ef−Lmax).

摘要： Multi-resonant control of a 3 degree-of-freedom (heave-pitch-surge) wave energy converter enables energy capture that can be in the order of three times the energy capture of a heave-only wave energy converter. The invention uses a time domain feedback control strategy that is optimal based on the criteria of complex conjugate control. The multi-resonant control can also be used to shift the harvested energy from one of the coupled modes to another, enabling the elimination of one of the actuators otherwise required in a 3 degree-of-freedom wave energy converter. This feedback control strategy does not require wave prediction; it only requires the measurement of the buoy position and velocity.

摘要： A control device controls a hydraulic cylinder unit having a piston. The device receives a setpoint variable and an actual variable and determines, based on a difference between the setpoint variable and the actual variable, a preliminary manipulated variable for valves of the hydraulic cylinder unit. The setpoint variable and the actual variable relate to a position of the piston or a force applied by the piston. Linearization factors are determined dynamically as a function of the actual position of the piston and working pressures on both sides of the piston and a hydraulic fluid tank/pump. Definitive manipulated variables to control the valves are determined from the preliminary manipulated variable and the linearization factors. With the linearization factors, a ratio of the piston adjustment speed to the difference between the setpoint variable and the actual variable is independent of the actual position of the piston and the working pressures.

摘要： A multi-resonant wide band controller decomposes the wave energy converter control problem into sub-problems; an independent single-frequency controller is used for each sub-problem. Thus, each sub-problem controller can be optimized independently. The feedback control enables actual time-domain realization of multi-frequency complex conjugate control. The feedback strategy requires only measurements of the buoy position and velocity. No knowledge of excitation force, wave measurements, nor wave prediction is needed. As an example, the feedback signal processing can be carried out using Fast Fourier Transform with Hanning windows and optimization of amplitudes and phases. Given that the output signal is decomposed into individual frequencies, the implementation of the control is very simple, yet generates energy similar to the complex conjugate control.
