LQGRegulator

LQGRegulator[{ssm, sensors, finputs}, {w, v, h}, {q, r, p}]
constructs the optimal feedback regulator for the StateSpaceModel ssm using noisy measurements sensors and feedback inputs finputs. The process, measurement, and cross-covariance matrices are w, v, and h; and the state, input, and state-input weighting matrices are q, r, and p.

LQGRegulator[{ssm, sensors, finputs, einputs}, {...}, {...}]
specifies einputs as the exogenous deterministic inputs.

Details and OptionsDetails and Options

  • The standard state-space model ssm can be given as StateSpaceModel[{a, b, c, d}], where a, b, c, and d represent the state, input, output, and transmission matrices in either a continuous-time or a discrete-time system:
  • continuous-time system
    discrete-time system
  • The descriptor state-space model ssm can be given as StateSpaceModel[{a, b, c, d, e}] in either continuous time or discrete time:
  • continuous-time system
    discrete-time system
  • The input can include stochastic inputs , feedback inputs , and exogenous deterministic inputs .
  • The arguments finputs and einputs are lists of integers specifying the positions of and in .
  • The output consists of the noisy measurements as well as other outputs.
  • The argument sensors is a list of integers specifying the positions of in .
  • LQGRegulator[{ssm, sensors, finputs}, {...}, {...}] is equivalent to LQGRegulator[{ssm, sensors, finputs, None}, {...}].
  • If not specified, h and p are assumed to be zero matrices.
  • Block diagram of the continuous-time system with its regulator:
  • Block diagram of the discrete-time system with its regulator:
  • The system with the regulator has the following block diagram:
