ControlSystems - v1.0.0

ControlSystems v1.0.0

Diff since v0.12.17

• Breaking: Frequency-responses have changed data layout to ny×nu×nω from the previous nω×ny×nu. This is for performance reasons and to be consistent with time responses. This affects downstream functions bode and nyquist as well.
• Breaking: baltrunc and balreal now return the diagonal of the Gramian as the second argument rather than the full matrix.
• Breaking: The pid constructor no longer takes parameters as keyword arguments. pid has also gotten some new features, the new signature is pid(P, I, D=0; form = :standard, Ts=nothing, Tf=nothing, state_space=false). This change affects downstream functions like placePI, loopshapingPI, pidplots.
• Breaking: The semantics of broadcasted multiplication between two systems was previously inconsistent between StateSpace and TransferFunction. The new behavior is documented under Multiplying systems in the documentation. The new semantics is stricter than before, and some multiplication statements that previously used implicit broadcasting will now error with a message suggesting explicit broadcasting.

• Breaking: Plots.jl is no longer loaded by ControlSystems.jl. This improves loading times for the package, but means that users will have to run using Plots manually before plotting functions are available.
• Deprecations: Functions dare/dlyap/dkalman/dlqr are now deprecated in favor of an interface that uses dispatch on the types Continuous / Discrete. Example: dare(A,B,Q,R) is now are(Discrete,A,B,Q,R) or are(sysd,Q,R).

ControlSystems - v0.7.0

This version introduces a new type TimeEvolution to represent what was previously called Ts, i.e., the sample time for a discrete system or continuous (previously indicated by Ts = -1. You can still access the sample time for a discrete systems with the property .Ts.

This new type is part of the type definition of LTIsystems, i.e., the full type of a state-space object is now on the form ```julia julia> ss(1) StateSpace{Continuous,Int64,Array{Int64,2}} D = 1

Continuous-time state-space model ```

Some new functions: - timeevol(Lti) -> TimeEvolution (not exported) - isdiscrete

ControlSystems - Major revision with parametric types

Some important changes: - LTISystem types are now more generic and can hold matrices/vectors of arbitrary type - Continuous time systems are simulated with continuous time solvers from OrdinaryDiffEq.jl - Freqresp now returns frequencies in the first dimension. - Breaking: lsim(sys, u::Function) syntax has changed from u(t,x) to u(x,t) to be consistent with OrdinaryDiffEq - Breaking: feedback(P,C) no longer returns feedback(P*C). The behavior is changed to feedback(P1, P2) = P1/(1+P1*P2). - Type Simulator provides lower level interface to continuous time simulation.
