The control system tuning tools such as
Control System Tuner automatically tune control systems from high-level
tuning goals you specify, such as reference tracking, disturbance
rejection, and stability margins. The software jointly tunes all the
free parameters of your control system regardless of control system
architecture or the number of feedback loops it contains. For example,
the model of the following illustration represents a multiloop control
system for a helicopter.
This control system includes a number of fixed elements, such
as the helicopter model itself and the roll-off filters. The inner
control loop provides static output feedback for decoupling. The outer
loop includes PI controllers for setpoint tracking. The tuning tools
jointly optimize the gains in the
to meet setpoint tracking, stability margin, and other requirements
that you specify. These tools allow you to specify any control structure
and designate which blocks in your system are tunable.
Control systems are tuned to meet your specific performance and robustness goals subject to feasibility constraints such as actuator limits, sensor accuracy, computing power, or energy consumption. The library of tuning goals lets you capture these objectives in a form suitable for fast automated tuning. This library includes standard control objectives such as reference tracking, disturbance rejection, loop shapes, closed-loop damping, and stability margins. Using these tools, you can perform multi-objective tuning of control systems having any structure.
