    Using the widely accepted philosophy that simple control design procedures are of great value in producing acceptable controllers for plant with a degree of dynamic and/or structural simplicity, particularly in the situation where closed-loop performance requirements are modest, recent work on the use of approximate models and plant step data in multivariable design is applied to produce simple, r...

    The optimal fixed-lag deconvolution smoothing problem is solved in the frequency domain. It is shown how the smoother may be implemented online by using an innovations moving average description, thus avoiding a two-pass algorithm, involving causal and anticausal filtering. The optimal smoother is given in polynomial matrix form, which makes the solution relatively simple to implement. View full abstract»

  • Controllers for LQG self-tuning applications with coloured measurement noise and dynamic costing

    The usual plant structure assumed in self-tuning problems is not sufficiently general to cover some industrial control problems, such as autopilot design. An LQG-based control law is developed for this type of industrial situation. The cost function includes dynamic weighting elements, which allows integral action to be introduced and robustness characteristics to be modified. The system model inv... View full abstract»

  • Model reduction of discrete systems using the power decomposition method and the system identification method

    Publication Year: 1986, Page(s):30 - 34

    A mixed method of discrete system model reduction retaining the advantages of the power decomposition method and the system identification method is proposed. From the viewpoint of energy contributions to the system output, the dynamic modes with dominant energy contributions, instead of those with dominant eigenvalues, will be preserved by power decomposition method. Having determined the denomin... View full abstract»

  • Range-space dynamics of scalar-variable-structure control systems

    The dynamic behaviour of the range space of a linear operator mt used to form a switching function in a scalar-variable-structure control system is described. It is shown that as the operator mt is defined for less than the full-state vector complement, the dynamic order of the range space increases. It is also shown that the range space can be stabilised by compensation techniques, without affect... View full abstract»
